+          <p>When a <span class="pop" id="bookie-popover">bookie</span> crashes, all <span class="pop" id="ledger-popover">ledgers</span> on that bookie become under-replicated. In order to bring all ledgers in your BookKeeper cluster back to full replication, you’ll need to <em>recover</em> the data from any offline bookies. There are two ways to recover bookies’ data:</p>
+
+<ol>
+  <li>Using <a href="#manual-recovery">manual recovery</a></li>
+  <li>Automatically, using <a href="#autorecovery"><em>AutoRecovery</em></a></li>
+</ol>
+
+<h2 id="manual-recovery">Manual recovery</h2>
+
+<p>You can manually recover failed bookies using the <a href="../../reference/cli"><code class="highlighter-rouge">bookkeeper</code></a> command-line tool. You need to specify:</p>
+
+<ul>
+  <li>the <code class="highlighter-rouge">shell recover</code> option</li>
+  <li>the IP and port for the failed bookie</li>
+</ul>
+
+<p>Here’s an example:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell recover <span class="se">\</span>
+  192.168.1.10:3181      <span class="c"># IP and port for the failed bookie</span>
+</code></pre></div></div>
+
+<p>If you wish, you can also specify which ledgers you’d like to recover. Here’s an example:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell recover <span class="se">\</span>
+  192.168.1.10:3181 <span class="se">\ </span>   <span class="c"># IP and port for the failed bookie</span>
+  <span class="nt">--ledger</span> ledgerID      <span class="c"># ledgerID which you want to recover </span>
+</code></pre></div></div>
+
+<h3 id="the-manual-recovery-process">The manual recovery process</h3>
+
+<p>When you initiate a manual recovery process, the following happens:</p>
+
+<ol>
+  <li>The client (the process running ) reads the metadata of active ledgers from ZooKeeper.</li>
+  <li>The ledgers that contain fragments from the failed bookie in their ensemble are selected.</li>
+  <li>A recovery process is initiated for each ledger in this list and the rereplication process is run for each ledger.</li>
+  <li>Once all the ledgers are marked as fully replicated, bookie recovery is finished.</li>
+</ol>
+
+<h2 id="autorecovery">AutoRecovery</h2>
+
+<p>AutoRecovery is a process that:</p>
+
+<ul>
+  <li>automatically detects when a <span class="pop" id="bookie-popover">bookie</span> in your BookKeeper cluster has become unavailable and then</li>
+  <li>rereplicates all the <span class="pop" id="ledger-popover">ledgers</span> that were stored on that bookie.</li>
+</ul>
+
+<p>AutoRecovery can be run in three ways:</p>
+
+<ol>
+  <li>On dedicated nodes in your BookKeeper cluster</li>
+  <li>On the same machines on which your bookies are running</li>
+  <li>On a combination of autorecovery nodes and bookie nodes</li>
+</ol>
+
+<h2 id="running-autorecovery">Running AutoRecovery</h2>
+
+<p>You can start up AutoRecovery using the <a href="../../reference/cli#bookkeeper-autorecovery"><code class="highlighter-rouge">autorecovery</code></a> command of the <a href="../../reference/cli"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool.</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper autorecovery
+</code></pre></div></div>
+
+<blockquote>
+  <p>The most important thing to ensure when starting up AutoRecovery is that the ZooKeeper connection string specified by the <a href="../../reference/config#zkServers"><code class="highlighter-rouge">zkServers</code></a> parameter points to the right ZooKeeper cluster.</p>
+</blockquote>
+
+<p>If you start up AutoRecovery on a machine that is already running a bookie, then the AutoRecovery process will run alongside the bookie on a separate thread.</p>
+
+<p>You can also start up AutoRecovery on a fresh machine if you’d like to create a dedicated cluster of AutoRecovery nodes.</p>
+
+<p>Note that if you <em>only</em> want the AutoRecovery process to run on your dedicated AutoRecovery nodes, you must set <code class="highlighter-rouge">autoRecoveryDaemonEnabled</code> to <code class="highlighter-rouge">false</code> in the <code class="highlighter-rouge">bookkeeper</code> configuration. Otherwise,
+bookkeeper nodes will also handle rereplication work.</p>
+
+<h2 id="configuration">Configuration</h2>
+
+<p>There are a handful of AutoRecovery-related configs in the <a href="../../reference/config"><code class="highlighter-rouge">bk_server.conf</code></a> configuration file. For a listing of those configs, see <a href="../../reference/config#autorecovery-settings">AutoRecovery settings</a>.</p>
+
+<h2 id="disable-autorecovery">Disable AutoRecovery</h2>
+
+<p>You can disable AutoRecovery for the whole cluster at any time, for example during maintenance. Disabling AutoRecovery ensures that bookies’ data isn’t unnecessarily rereplicated when the bookie is only taken down for a short period of time, for example when the bookie is being updated or the configuration if being changed.</p>
+
+<p>You can disable AutoRecover for the whole cluster using the <a href="../../reference/cli#bookkeeper-shell-autorecovery"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell autorecovery <span class="nt">-disable</span>
+</code></pre></div></div>
+
+<p>Once disabled, you can reenable AutoRecovery for the whole cluster using the <a href="../../reference/cli#bookkeeper-shell-autorecovery"><code class="highlighter-rouge">enable</code></a> shell command:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell autorecovery <span class="nt">-enable</span>
+</code></pre></div></div>
+
+<h2 id="autorecovery-architecture">AutoRecovery architecture</h2>
+
+<p>AutoRecovery has two components:</p>
+
+<ol>
+  <li>The <a href="#auditor"><strong>auditor</strong></a> (see the <a href="../../api/javadoc/org/apache/bookkeeper/replication/Auditor.html"><code class="highlighter-rouge">Auditor</code></a> class) is a singleton node that watches bookies to see if they fail and creates rereplication tasks for the ledgers on failed bookies.</li>
+  <li>The <a href="#replication-worker"><strong>replication worker</strong></a> (see the <a href="../../api/javadoc/org/apache/bookkeeper/replication/ReplicationWorker.html"><code class="highlighter-rouge">ReplicationWorker</code></a> class) runs on each bookie and executes rereplication tasks provided by the auditor.</li>
+</ol>
+
+<p>Both of these components run as threads in the <a href="../../api/javadoc/org/apache/bookkeeper/replication/AutoRecoveryMain"><code class="highlighter-rouge">AutoRecoveryMain</code></a> process, which runs on each bookie in the cluster. All recovery nodes participate in leader election—using ZooKeeper—to decide which node becomes the auditor. Nodes that fail to become the auditor watch the elected auditor and run an election process again if they see that the auditor node has failed.</p>
+
+<h3 id="auditor">Auditor</h3>
+
+<p>The auditor watches all bookies in the cluster that are registered with ZooKeeper. Bookies register with ZooKeeper at startup. If the bookie crashes or is killed, the bookie’s registration in ZooKeeper disappears and the auditor is notified of the change in the list of registered bookies.</p>
+
+<p>When the auditor sees that a bookie has disappeared, it immediately scans the complete <span class="pop" id="ledger-popover">ledger</span> list to find ledgers that have data stored on the failed bookie. Once it has a list of ledgers for that bookie, the auditor will publish a rereplication task for each ledger under the <code class="highlighter-rouge">/underreplicated/</code> <a href="https://zookeeper.apache.org/doc/current/zookeeperOver.html">znode</a> in ZooKeeper.</p>
+
+<h3 id="replication-worker">Replication Worker</h3>
+
+<p>Each replication worker watches for tasks being published by the auditor on the <code class="highlighter-rouge">/underreplicated/</code> znode in ZooKeeper. When a new task appears, the replication worker will try to get a lock on it. If it cannot acquire the lock, it will try the next entry. The locks are implemented using ZooKeeper ephemeral znodes.</p>
+
+<p>The replication worker will scan through the rereplication task’s ledger for fragments of which its local bookie is not a member. When it finds fragments matching this criterion, it will replicate the entries of that fragment to the local bookie. If, after this process, the ledger is fully replicated, the ledgers entry under /underreplicated/ is deleted, and the lock is released. If there is a problem replicating, or there are still fragments in the ledger which are still underreplicated (due to the local bookie already being part of the ensemble for the fragment), then the lock is simply released.</p>
+
+<p>If the replication worker finds a fragment which needs rereplication, but does not have a defined endpoint (i.e. the final fragment of a ledger currently being written to), it will wait for a grace period before attempting rereplication. If the fragment needing rereplication still does not have a defined endpoint, the ledger is fenced and rereplication then takes place.</p>
+
+<p>This avoids the situation in which a client is writing to a ledger and one of the bookies goes down, but the client has not written an entry to that bookie before rereplication takes place. The client could continue writing to the old fragment, even though the ensemble for the fragment had changed. This could lead to data loss. Fencing prevents this scenario from happening. In the normal case, the client will try to write to the failed bookie within the grace period, and will have started a new fragment before rereplication starts.</p>
+
+<p>You can configure this grace period using the <a href="../../reference/config#openLedgerRereplicationGracePeriod"><code class="highlighter-rouge">openLedgerRereplicationGracePeriod</code></a> parameter.</p>
+
+<h3 id="the-rereplication-process">The rereplication process</h3>
+
+<p>The ledger rereplication process happens in these steps:</p>
+
+<ol>
+  <li>The client goes through all ledger fragments in the ledger, selecting those that contain the failed bookie.</li>
+  <li>A recovery process is initiated for each ledger fragment in this list.
+    <ol>
+      <li>The client selects a bookie to which all entries in the ledger fragment will be replicated; In the case of autorecovery, this will always be the local bookie.</li>
+      <li>The client reads entries that belong to the ledger fragment from other bookies in the ensemble and writes them to the selected bookie.</li>
+      <li>Once all entries have been replicated, the zookeeper metadata for the fragment is updated to reflect the new ensemble.</li>
+      <li>The fragment is marked as fully replicated in the recovery tool.</li>
+    </ol>
+  </li>
+  <li>Once all ledger fragments are marked as fully replicated, the ledger is marked as fully replicated.</li>
+</ol>

+
+      <div class="content">
+        <section class="bk-main-content">
+          <p>This document is a guide to deploying, administering, and maintaining BookKeeper. It also discusses <a href="#best-practices">best practices</a> and <a href="#common-problems">common problems</a>.</p>
+
+<h2 id="requirements">Requirements</h2>
+
+<p>A typical BookKeeper installation consists of an ensemble of <span class="pop" id="bookie-popover">bookies</span> and a ZooKeeper quorum. The exact number of bookies depends on the quorum mode that you choose, desired throughput, and the number of clients using the installation simultaneously.</p>
+
+<p>The minimum number of bookies depends on the type of installation:</p>
+
+<ul>
+  <li>For <em>self-verifying</em> entries you should run at least three bookies. In this mode, clients store a message authentication code along with each <span class="pop" id="entry-popover">entry</span>.</li>
+  <li>For <em>generic</em> entries you should run at least four</li>
+</ul>
+
+<p>There is no upper limit on the number of bookies that you can run in a single ensemble.</p>
+
+<h3 id="performance">Performance</h3>
+
+<p>To achieve optimal performance, BookKeeper requires each server to have at least two disks. It’s possible to run a bookie with a single disk but performance will be significantly degraded.</p>
+
+<h3 id="zookeeper">ZooKeeper</h3>
+
+<p>There is no constraint on the number of ZooKeeper nodes you can run with BookKeeper. A single machine running ZooKeeper in <a href="https://zookeeper.apache.org/doc/current/zookeeperStarted.html#sc_InstallingSingleMode">standalone mode</a> is sufficient for BookKeeper, although for the sake of higher resilience we recommend running ZooKeeper in <a href="https://zookeeper.apache.org/doc/current/zookeeperStarted.html#sc_RunningReplicatedZooKeeper">quorum mode</a> with multiple servers.</p>
+
+<h2 id="starting-and-stopping-bookies">Starting and stopping bookies</h2>
+
+<p>You can run bookies either in the foreground or in the background, using <a href="https://en.wikipedia.org/wiki/Nohup">nohup</a>. You can also run <a href="#local-bookie">local bookies</a> for development purposes.</p>
+
+<p>To start a bookie in the foreground, use the <a href="../../reference/cli#bookkeeper-bookie"><code class="highlighter-rouge">bookie</code></a> command of the <a href="../../reference/cli#bookkeeper"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper bookie
+</code></pre></div></div>
+
+<p>To start a bookie in the background, use the <a href="../../reference/cli#bookkeeper-daemon.sh"><code class="highlighter-rouge">bookkeeper-daemon.sh</code></a> script and run <code class="highlighter-rouge">start bookie</code>:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper-daemon.sh start bookie
+</code></pre></div></div>
+
+<h3 id="local-bookies">Local bookies</h3>
+
+<p>The instructions above showed you how to run bookies intended for production use. If you’d like to experiment with ensembles of bookies locally, you can use the <a href="../../reference/cli#bookkeeper-localbookie"><code class="highlighter-rouge">localbookie</code></a> command of the <code class="highlighter-rouge">bookkeeper</code> CLI tool and specify the number of bookies you’d like to run.</p>
+
+<p>This would spin up a local ensemble of 6 bookies:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper localbookie 6
+</code></pre></div></div>
+
+<blockquote>
+  <p>When you run a local bookie ensemble, all bookies run in a single JVM process.</p>
+</blockquote>
+
+<h2 id="configuring-bookies">Configuring bookies</h2>
+
+<p>There’s a wide variety of parameters that you can set in the bookie configuration file in <code class="highlighter-rouge">bookkeeper-server/conf/bk_server.conf</code> of your <a href="../../reference/config">BookKeeper installation</a>. A full listing can be found in <a href="../../reference/config">Bookie configuration</a>.</p>
+
+<p>Some of the more important parameters to be aware of:</p>

+  </tbody>
+</table>
+
+<blockquote>
+  <p>Ideally, the directories specified <code class="highlighter-rouge">journalDirectory</code> and <code class="highlighter-rouge">ledgerDirectories</code> should be on difference devices.</p>
+</blockquote>
+
+<h2 id="logging">Logging</h2>
+
+<p>BookKeeper uses <a href="http://www.slf4j.org/">slf4j</a> for logging, with <a href="https://logging.apache.org/log4j/2.x/">log4j</a> bindings enabled by default.</p>
+
+<p>To enable logging for a bookie, create a <code class="highlighter-rouge">log4j.properties</code> file and point the <code class="highlighter-rouge">BOOKIE_LOG_CONF</code> environment variable to the configuration file. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span><span class="nb">export </span><span class="nv">BOOKIE_LOG_CONF</span><span class="o">=</span>/some/path/log4j.properties
+<span class="nv">$ </span>bin/bookkeeper bookie
+</code></pre></div></div>
+
+<h2 id="upgrading">Upgrading</h2>
+
+<p>From time to time you may need to make changes to the filesystem layout of bookies—changes that are incompatible with previous versions of BookKeeper and require that directories used with previous versions are upgraded. If a filesystem upgrade is required when updating BookKeeper, the bookie will fail to start and return an error like this:</p>
+
+<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>2017-05-25 10:41:50,494 - ERROR - [main:Bookie@246] - Directory layout version is less than 3, upgrade needed
+</code></pre></div></div>
+
+<p>BookKeeper provides a utility for upgrading the filesystem. You can perform an upgrade using the <a href="../../reference/cli#bookkeeper-upgrade"><code class="highlighter-rouge">upgrade</code></a> command of the <code class="highlighter-rouge">bookkeeper</code> CLI tool. When running <code class="highlighter-rouge">bookkeeper upgrade</code> you need to specify one of three flags:</p>
+
+<table>
+  <thead>
+    <tr>
+      <th style="text-align: left">Flag</th>
+      <th style="text-align: left">Action</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--upgrade</code></td>
+      <td style="text-align: left">Performs an upgrade</td>
+    </tr>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--rollback</code></td>
+      <td style="text-align: left">Performs a rollback to the initial filesystem version</td>
+    </tr>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--finalize</code></td>
+      <td style="text-align: left">Marks the upgrade as complete</td>
+    </tr>
+  </tbody>
+</table>
+
+<h3 id="upgrade-pattern">Upgrade pattern</h3>
+
+<p>A standard upgrade pattern is to run an upgrade…</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper upgrade <span class="nt">--upgrade</span>
+</code></pre></div></div>
+
+<p>…then check that everything is working normally, then kill the bookie. If everything is okay, finalize the upgrade…</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper upgrade <span class="nt">--finalize</span>
+</code></pre></div></div>
+
+<p>…and then restart the server:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper bookie
+</code></pre></div></div>
+
+<p>If something has gone wrong, you can always perform a rollback:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper upgrade <span class="nt">--rollback</span>
+</code></pre></div></div>
+
+<h2 id="formatting">Formatting</h2>
+
+<p>You can format bookie metadata in ZooKeeper using the <a href="../../reference/cli#bookkeeper-shell-metaformat"><code class="highlighter-rouge">metaformat</code></a> command of the <a href="../../reference/cli#the-bookkeeper-shell">BookKeeper shell</a>.</p>
+
+<p>By default, formatting is done in interactive mode, which prompts you to confirm the format operation if old data exists. You can disable confirmation using the <code class="highlighter-rouge">-nonInteractive</code> flag. If old data does exist, the format operation will abort <em>unless</em> you set the <code class="highlighter-rouge">-force</code> flag. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell metaformat
+</code></pre></div></div>
+
+<p>You can format the local filesystem data on a bookie using the <a href="../../reference/cli#bookkeeper-shell-bookieformat"><code class="highlighter-rouge">bookieformat</code></a> command on each bookie. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell bookieformat
+</code></pre></div></div>
+
+<blockquote>
+  <p>The <code class="highlighter-rouge">-force</code> and <code class="highlighter-rouge">-nonInteractive</code> flags are also available for the <code class="highlighter-rouge">bookieformat</code> command.</p>
+</blockquote>
+
+<h2 id="autorecovery">AutoRecovery</h2>
+
+<p>For a guide to AutoRecovery in BookKeeper, see <a href="../autorecovery">this doc</a>.</p>
+
+<h2 id="missing-disks-or-directories">Missing disks or directories</h2>
+
+<p>Accidentally replacing disks or removing directories can cause a bookie to fail while trying to read a ledger fragment that, according to the ledger metadata, exists on the bookie. For this reason, when a bookie is started for the first time, its disk configuration is fixed for the lifetime of that bookie. Any change to its disk configuration, such as a crashed disk or an accidental configuration change, will result in the bookie being unable to start. That will throw an error like this:</p>
+
+<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>2017-05-29 18:19:13,790 - ERROR - [main:BookieServer314] – Exception running bookie server : @
+org.apache.bookkeeper.bookie.BookieException$InvalidCookieException
+.......at org.apache.bookkeeper.bookie.Cookie.verify(Cookie.java:82)
+.......at org.apache.bookkeeper.bookie.Bookie.checkEnvironment(Bookie.java:275)
+.......at org.apache.bookkeeper.bookie.Bookie.&lt;init&gt;(Bookie.java:351)
+</code></pre></div></div>
+
+<p>If the change was the result of an accidental configuration change, the change can be reverted and the bookie can be restarted. However, if the change <em>cannot</em> be reverted, such as is the case when you want to add a new disk or replace a disk, the bookie must be wiped and then all its data re-replicated onto it.</p>
+
+<ol>
+  <li>Increment the <a href="../../reference/config#bookiePort"><code class="highlighter-rouge">bookiePort</code></a> parameter in the <a href="../../reference/config"><code class="highlighter-rouge">bk_server.conf</code></a></li>
+  <li>Ensure that all directories specified by <a href="../../reference/config#journalDirectory"><code class="highlighter-rouge">journalDirectory</code></a> and <a href="../../reference/config#ledgerDirectories"><code class="highlighter-rouge">ledgerDirectories</code></a> are empty.</li>
+  <li><a href="#starting-and-stopping-bookies">Start the bookie</a>.</li>
+  <li>
+    <p>Run the following command to re-replicate the data:</p>
+
+    <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell recover &lt;oldbookie&gt; 
+</code></pre></div>    </div>
+
+    <p>The ZooKeeper server, old bookie, and new bookie, are all identified by their external IP and <code class="highlighter-rouge">bookiePort</code> (3181 by default). Here’s an example:</p>
+
+    <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bin/bookkeeper shell recover  192.168.1.10:3181

+          <p>In case the user wants to decommission a bookie, the following process is useful to follow in order to verify if the
+decommissioning was safely done.</p>
+
+<h3 id="before-we-decommission">Before we decommission</h3>
+<ol>
+  <li>
+    <p>Ensure state of your cluster can support the decommissioning of the target bookie.
+Check if <code class="highlighter-rouge">EnsembleSize &gt;= Write Quorum &gt;= Ack Quorum</code> stays true with one less bookie</p>
+  </li>
+  <li>
+    <p>Ensure target bookie shows up in the listbookies command.</p>
+  </li>
+  <li>
+    <p>Ensure that there is no other process ongoing (upgrade etc).</p>
+  </li>
+</ol>
+
+<h3 id="process-of-decommissioning">Process of Decommissioning</h3>
+<ol>
+  <li>Log on to the bookie node, check if there are underreplicated ledgers.</li>
+</ol>
+
+<p>If there are, the decommission command will force them to be replicated.
+<code class="highlighter-rouge">$ bin/bookkeeper shell listunderreplicated</code></p>
+
+<ol>
+  <li>
+    <p>Stop the bookie
+<code class="highlighter-rouge">$ bin/bookkeeper-daemon.sh stop bookie</code></p>
+  </li>
+  <li>
+    <p>Run the decommission command.
+If you have logged onto the node you wish to decommission, you don’t need to provide <code class="highlighter-rouge">-bookieid</code>
+If you are running the decommission command for target bookie node from another bookie node you should mention 
+the target bookie id in the arguments for <code class="highlighter-rouge">-bookieid</code>
+<code class="highlighter-rouge">$ bin/bookkeeper shell decommissionbookie</code>
+or
+<code class="highlighter-rouge">$ bin/bookkeeper shell decommissionbookie -bookieid &lt;target bookieid&gt;</code></p>
+  </li>
+  <li>
+    <p>Validate that there are no ledgers on decommissioned bookie
+<code class="highlighter-rouge">$ bin/bookkeeper shell listledgers -bookieid &lt;target bookieid&gt;</code></p>
+  </li>
+</ol>
+
+<p>Last step to verify is you could run this command to check if the bookie you decommissioned doesn’t show up in list bookies:</p>

+</blockquote>
+
+<h2 id="overview">Overview</h2>
+
+<p>Consider the below guidelines in preparation for upgrading.</p>
+
+<ul>
+  <li>Always back up all your configuration files before upgrading.</li>
+  <li>Read through the documentation and draft an upgrade plan that matches your specific requirements and environment before starting the upgrade process.
+  Put differently, don’t start working through the guide on a live cluster. Read guide entirely, make a plan, then execute the plan.</li>
+  <li>Pay careful consideration to the order in which components are upgraded. In general, you need to upgrade bookies first and then upgrade your clients.</li>
+  <li>If autorecovery is running along with bookies, you need to pay attention to the upgrade sequence.</li>
+  <li>Read the release notes carefully for each release. They contain not only information about noteworthy features, but also changes to configurations
+  that may impact your upgrade.</li>
+  <li>Always upgrade one or a small set of bookies to canary new version before upgraing all bookies in your cluster.</li>
+</ul>
+
+<h2 id="canary">Canary</h2>
+
+<p>It is wise to canary an upgraded version in one or small set of bookies before upgrading all bookies in your live cluster.</p>
+
+<p>You can follow below steps on how to canary a upgraded version:</p>
+
+<ol>
+  <li>Stop a Bookie.</li>
+  <li>Upgrade the binary and configuration.</li>
+  <li>Start the Bookie in <code class="highlighter-rouge">ReadOnly</code> mode. This can be used to verify if the Bookie of this new version can run well for read workload.</li>
+  <li>Once the Bookie is running at <code class="highlighter-rouge">ReadOnly</code> mode successfully for a while, restart the Bookie in <code class="highlighter-rouge">Write/Read</code> mode.</li>
+  <li>After step 4, the Bookie will serve both write and read traffic.</li>
+</ol>
+
+<h3 id="rollback-canaries">Rollback Canaries</h3>
+
+<p>If problems occur during canarying an upgraded version, you can simply take down the problematic Bookie node. The remain bookies in the old cluster
+will repair this problematic bookie node by autorecovery. Nothing needs to be worried about.</p>
+
+<h2 id="upgrade-steps">Upgrade Steps</h2>
+
+<p>Once you determined a version is safe to upgrade in a few nodes in your cluster, you can perform following steps to upgrade all bookies in your cluster.</p>
+
+<ol>
+  <li>Determine if autorecovery is running along with bookies. If yes, check if the clients (either new clients with new binary or old clients with new configurations)
+are allowed to talk to old bookies; if clients are not allowed to talk to old bookies, please <a href="../../reference/cli/#autorecovery-1">disable autorecovery</a> during upgrade.</li>
+  <li>Decide on performing a rolling upgrade or a downtime upgrade.</li>
+  <li>Upgrade all Bookies (more below)</li>
+  <li>If autorecovery was disabled during upgrade, <a href="../../reference/cli/#autorecovery-1">enable autorecovery</a>.</li>
+  <li>After all bookies are upgraded, build applications that use <code class="highlighter-rouge">BookKeeper client</code> against the new bookkeeper libraries and deploy the new versions.</li>
+</ol>
+
+<h3 id="upgrade-bookies">Upgrade Bookies</h3>
+
+<p>In a rolling upgrade scenario, upgrade one Bookie at a time. In a downtime upgrade scenario, take the entire cluster down, upgrade each Bookie, then start the cluster.</p>
+
+<p>For each Bookie:</p>
+
+<ol>
+  <li>Stop the bookie.</li>
+  <li>Upgrade the software (either new binary or new configuration)</li>
+  <li>Start the bookie.</li>
+</ol>
+
+<h2 id="upgrade-guides">Upgrade Guides</h2>
+
+<p>We describes the general upgrade method in Apache BookKeeper as above. We will cover the details for individual versions.</p>
+
+<h3 id="46x-to-470-upgrade">4.6.x to 4.7.0 upgrade</h3>
+
+<p>There isn’t any protocol related backward compabilities changes in 4.7.0. So you can follow the general upgrade sequence to upgrade from 4.6.x to 4.7.0.</p>

+<h3 id="47x-to-48x-upgrade">4.7.x to 4.8.X upgrade</h3>
+
+<p>In 4.8.x a new feature is added to persist explicitLac in FileInfo and explicitLac entry in Journal. (Note: Currently this feature is not available if your ledgerStorageClass is DbLedgerStorage, ISSUE #1533 is going to address it) Hence current journal format version is bumped to 6 and current FileInfo header version is bumped to 1. But since default config values of ‘journalFormatVersionToWrite’ and ‘fileInfoFormatVersionToWrite’ are set to older versions, this feature is off by default. To enable this feature those config values should be set to current versions. Once this is enabled then we cannot rollback to previous Bookie versions (4.7.x and older), since older version code would not be able to deal with explicitLac entry in Journal file while replaying journal and also reading Header of Index files / FileInfo would fail reading Index files with newer FileInfo version. So in summary, it is a non-rollbackable feature and it applies even if explicitLac is not being used.</p>
+
+<h3 id="45x-to-46x-upgrade">4.5.x to 4.6.x upgrade</h3>
+
+<p>There isn’t any protocol related backward compabilities changes in 4.6.x. So you can follow the general upgrade sequence to upgrade from 4.5.x to 4.6.x.</p>
+
+<h3 id="44x-to-45x-upgrade">4.4.x to 4.5.x upgrade</h3>
+
+<p>There isn’t any protocol related backward compabilities changes in 4.5.0. So you can follow the general upgrade sequence to upgrade from 4.4.x to 4.5.x.
+However, we list a list of things that you might want to know.</p>
+
+<ol>
+  <li>4.5.x upgrades netty from 3.x to 4.x. The memory usage pattern might be changed a bit. Netty 4 uses more direct memory. Please pay attention to your memory usage
+ and adjust the JVM settings accordingly.</li>
+  <li><code class="highlighter-rouge">multi journals</code> is a non-rollbackable feature. If you configure a bookie to use multiple journals on 4.5.x you can not roll the bookie back to use 4.4.x. You have
+ to take a bookie out and recover it if you want to rollback to 4.4.x.</li>
+</ol>
+
+<p>If you are planning to upgrade a non-secured cluster to a secured cluster enabling security features in 4.5.0, please read <a href="../../security/overview">BookKeeper Security</a> for more details.</p>

+  <p>DistributedLog began its life as a separate project under the Apache Foundation. It was merged into BookKeeper in 2017.</p>
+</blockquote>
+
+<p>The DistributedLog API is an easy-to-use interface for managing BookKeeper entries that enables you to use BookKeeper without needing to interact with <a href="../ledger-api">ledgers</a> directly.</p>
+
+<p>DistributedLog (DL) maintains sequences of records in categories called <em>logs</em> (aka <em>log streams</em>). <em>Writers</em> append records to DL logs, while <em>readers</em> fetch and process those records.</p>
+
+<h2 id="architecture">Architecture</h2>
+
+<p>The diagram below illustrates how the DistributedLog API works with BookKeeper:</p>
+
+<p><img src="/img/distributedlog.png" alt="DistributedLog API" /></p>
+
+<h2 id="logs">Logs</h2>
+
+<p>A <em>log</em> in DistributedLog is an ordered, immutable sequence of <em>log records</em>.</p>
+
+<p>The diagram below illustrates the anatomy of a log stream:</p>
+
+<p><img src="/img/logs.png" alt="DistributedLog log" /></p>
+
+<h3 id="log-records">Log records</h3>
+
+<p>Each log record is a sequence of bytes. Applications are responsible for serializing and deserializing byte sequences stored in log records.</p>
+
+<p>Log records are written sequentially into a <em>log stream</em> and assigned with a a unique sequence number called a DLSN (<strong>D</strong>istributed<strong>L</strong>og <strong>S</strong>equence <strong>N</strong>umber).</p>
+
+<p>In addition to a DLSN, applications can assign their own sequence number when constructing log records. Application-defined sequence numbers are known as <em>TransactionIDs</em> (or <em>txid</em>). Either a DLSN or a TransactionID can be used for positioning readers to start reading from a specific log record.</p>
+
+<h3 id="log-segments">Log segments</h3>
+
+<p>Each log is broken down into <em>log segments</em> that contain subsets of records. Log segments are distributed and stored in BookKeeper. DistributedLog rolls the log segments based on the configured <em>rolling policy</em>, which be either</p>
+
+<ul>
+  <li>a configurable period of time (such as every 2 hours), or</li>
+  <li>a configurable maximum size (such as every 128 MB).</li>
+</ul>
+
+<p>The data in logs is divided up into equally sized log segments and distributed evenly across <span class="pop" id="bookie-popover">bookies</span>. This allows logs to scale beyond a size that would fit on a single server and spreads read traffic across the cluster.</p>
+
+<h3 id="namespaces">Namespaces</h3>
+
+<p>Log streams that belong to the same organization are typically categorized and managed under a <em>namespace</em>. DistributedLog namespaces essentially enable applications to locate log streams. Applications can perform the following actions under a namespace:</p>
+
+<ul>
+  <li>create streams</li>
+  <li>delete streams</li>
+  <li>truncate streams to a given sequence number (either a DLSN or a TransactionID)</li>
+</ul>
+
+<h2 id="writers">Writers</h2>
+
+<p>Through the DistributedLog API, writers write data into logs of their choice. All records are appended into logs in order. The sequencing is performed by the writer, which means that there is only one active writer for a log at any given time.</p>
+
+<p>DistributedLog guarantees correctness when two writers attempt to write to the same log when a network partition occurs using a <em>fencing</em> mechanism in the log segment store.</p>
+
+<h3 id="write-proxy">Write Proxy</h3>
+
+<p>Log writers are served and managed in a service tier called the <em>Write Proxy</em> (see the diagram <a href="#architecture">above</a>). The Write Proxy is used for accepting writes from a large number of clients.</p>
+
+<h2 id="readers">Readers</h2>
+
+<p>DistributedLog readers read records from logs of their choice, starting with a provided position. The provided position can be either a DLSN or a TransactionID.</p>
+
+<p>Readers read records from logs in strict order. Different readers can read records from different positions in the same log.</p>
+
+<p>Unlike other pub-sub systems, DistributedLog doesn’t record or manage readers’ positions. This means that tracking is the responsibility of applications, as different applications may have different requirements for tracking and coordinating positions. This is hard to get right with a single approach. Distributed databases, for example, might store reader positions along with SSTables, so they would resume applying transactions from the positions store in SSTables. Tracking reader positions could easily be done at the application level using various stores (such as ZooKeeper, the filesystem, or key-value stores).</p>
+
+<h3 id="read-proxy">Read Proxy</h3>
+
+<p>Log records can be cached in a service tier called the <em>Read Proxy</em> to serve a large number of readers. See the diagram <a href="#architecture">above</a>. The Read Proxy is the analogue of the <a href="#write-proxy">Write Proxy</a>.</p>
+
+<h2 id="guarantees">Guarantees</h2>
+
+<p>The DistributedLog API for BookKeeper provides a number of guarantees for applications:</p>
+
+<ul>
+  <li>Records written by a <a href="#writers">writer</a> to a <a href="#logs">log</a> are appended in the order in which they are written. If a record <strong>R1</strong> is written by the same writer as a record <strong>R2</strong>, <strong>R1</strong> will have a smaller sequence number than <strong>R2</strong>.</li>
+  <li><a href="#readers">Readers</a> see <a href="#log-records">records</a> in the same order in which they are <a href="#writers">written</a> to the log.</li>
+  <li>All records are persisted on disk by BookKeeper before acknowledgements, which guarantees durability.</li>
+  <li>For a log with a replication factor of N, DistributedLog tolerates up to N-1 server failures without losing any records.</li>
+</ul>
+
+<h2 id="api">API</h2>
+
+<p>Documentation for the DistributedLog API can be found <a href="https://bookkeeper.apache.org/distributedlog/docs/latest/user_guide/api/core">here</a>.</p>

+<blockquote>
+  <p>At a later date, the DistributedLog API docs will be added here.</p>

+
+The DistributedLog core library is written in Java and interacts with namespaces and logs directly.
+
+### Installation
+
+The BookKeeper Java client library is available via [Maven Central](http://search.maven.org/) and can be installed using [Maven](#maven), [Gradle](#gradle), and other build tools.
+
+### Maven
+
+If you're using [Maven](https://maven.apache.org/), add this to your [`pom.xml`](https://maven.apache.org/guides/introduction/introduction-to-the-pom.html) build configuration file:
+
+```xml
+<-- in your <properties> block ->
+<bookkeeper.version>4.12.1</bookkeeper.version>
+
+<-- in your <dependencies> block ->
+<dependency>
+  <groupId>org.apache.bookkeeper</groupId>
+  <artifactId>bookkeeper-server</artifactId>
+  <version>${bookkeeper.version}</version>
+</dependency>
+```
+
+### Gradle
+
+If you're using [Gradle](https://gradle.org/), add this to your [`build.gradle`](https://spring.io/guides/gs/gradle/) build configuration file:
+
+```groovy
+dependencies {
+    compile group: 'org.apache.bookkeeper', name: 'bookkeeper-server', version: '4.13.0'
+}
+
+// Alternatively:
+dependencies {
+    compile 'org.apache.bookkeeper:bookkeeper-server:4.13.0'
+}
+```
+
+### Namespace API
+
+A DL [namespace](#namespace) is a collection of [log streams](#log-streams). When using the DistributedLog API with BookKeeper, you need to provide your Java client with a namespace URI. That URI consists of three elements:
+
+1. The `distributedlog-bk` scheme
+1. A connection string for your BookKeeper cluster. You have three options for the connection string:
+   * An entire ZooKeeper connection string, for example `zk1:2181,zk2:2181,zk3:2181`
+   * A host and port for one node in your ZooKeeper cluster, for example `zk1:2181`. In general, it's better to provide a full ZooKeeper connection string.
+   * If your ZooKeeper cluster can be discovered via DNS, you can provide the DNS name, for example `my-zookeeper-cluster.com`.
+1. A path that points to the location where logs are stored. This could be a ZooKeeper [znode](https://zookeeper.apache.org/doc/current/zookeeperOver.html).
+  
+This is the general structure of a namespace URI:
+
+```shell
+distributedlog-bk://{connection-string}/{path}
+```
+
+Here are some example URIs:
+
+```shell
+distributedlog-bk://zk1:2181,zk2:2181,zk3:2181/my-namespace # Full ZooKeeper connection string
+distributedlog-bk://localhost:2181/my-namespace             # Single ZooKeeper node
+distributedlog-bk://my-zookeeper-cluster.com/my-namespace   # DNS name for ZooKeeper
+```
+
+#### Creating namespaces
+
+In order to create namespaces, you need to use the command-line tool.
+
+```shell
+$ 
+```
+
+#### Using namespaces
+
+Once you have a namespace URI, you can build a namespace instance, which will be used for operating streams. Use the `DistributedLogNamespaceBuilder` to build a `DistributedLogNamespace` object, passing in a `DistributedLogConfiguration`, a URI, and optionally a stats logger and a feature provider.
+
+```java
+DistributedLogConfiguration conf = new DistributedLogConfiguration();
+URI uri = URI.create("distributedlog-bk://localhost:2181/my-namespace ");
+DistributedLogNamespaceBuilder builder = DistributedLogNamespaceBuilder.newBuilder();
+DistributedLogNamespace = builder
+        .conf(conf)           // Configuration for the namespace
+        .uri(uri)             // URI for the namespace
+        .statsLogger(...)     // Stats logger for statistics
+        .featureProvider(...) // Feature provider for controlling features
+        .build();
+```
+
+### Log API
+
+#### Creating logs
+
+You can create a log by calling the `createLog` method on a `DistributedLogNamespace` object, passing in a name for the log. This creates the log under the namespace but does *not* return a handle for operating the log.
+
+```java
+DistributedLogNamespace namespace = /* Create namespace */;
+try {
+    namespace.createLog("test-log");
+} catch (IOException e) }
+    // Handle the log creation exception
+}
+```
+
+#### Opening logs
+
+A `DistributedLogManager` handle will be returned when opening a log using the `openLog` function, which takes the name of the log. This handle can be used for writing records to or reading records from the log.
+
+> If the log doesn't exist and `createStreamIfNotExists` is set to `true` in the configuration, the log will be created automatically when writing the first record.
+
+```java
+DistributedLogConfiguration conf = new DistributedLogConfiguration();
+conf.setCreateStreamIfNotExists(true);
+DistributedLogNamespace namespace = DistributedLogNamespace.newBuilder()
+        .conf(conf)
+        // Other builder attributes
+        .build();
+DistributedLogManager logManager = namespace.openLog("test-log");
+```
+
+Sometimes, applications may open a log with a different configuration from the enclosing namespace. This can be done using the same `openLog` method:
+
+```java
+// Namespace configuration
+DistributedLogConfiguration namespaceConf = new DistributedLogConfiguration();
+conf.setRetentionPeriodHours(24);
+URI uri = URI.create("distributedlog-bk://localhost:2181/my-namespace");
+DistributedLogNamespace namespace = DistributedLogNamespace.newBuilder()
+        .conf(namespaceConf)
+        .uri(uri)
+        // Other builder attributes
+        .build();
+// Log-specific configuration
+DistributedLogConfiguration logConf = new DistributedLogConfiguration();
+logConf.setRetentionPeriodHours(12);
+DistributedLogManager logManager = namespace.openLog(
+        "test-log",
+        Optional.of(logConf),
+        Optional.empty()
+);
+```
+
+#### Deleting logs
+
+The `DistributedLogNamespace` class provides `deleteLog` function that can be used to delete logs. When you delete a lot, the client library will attempt to acquire a lock on the log before deletion. If the log is being written to by an active writer, deletion will fail (as the other writer currently holds the lock).
+
+```java
+try {
+    namespace.deleteLog("test-log");
+} catch (IOException e) {
+    // Handle exception
+}
+```
+
+#### Checking for the existence of a log
+
+Applications can check whether a log exists by calling the `logExists` function.
+
+```java
+if (namespace.logExists("test-log")) {
+  // Perform some action when the log exists
+} else {
+  // Perform some action when the log doesn't exist
+}
+```
+
+#### Listing logs
+
+Applications can retrieve a list of all logs under a namespace using the `getLogs` function.
+
+```java
+Iterator<String> logs = namespace.getLogs();
+while (logs.hasNext()) {
+  String logName = logs.next();
+  // Do something with the log name, such as print
+}
+```
+
+### Writer API
+
+You can write to DistributedLog logs either [synchronously](#writing-to-logs-synchronously) using the `LogWriter` class or [asynchronously](#writing-to-logs-asynchronously) using the `AsyncLogWriter` class.
+
+#### Immediate flush
+
+By default, records are buffered rather than being written immediately. You can disable this behavior and make DL writers write ("flush") entries immediately by adding the following to your configuration object:
+
+```java
+conf.setImmediateFlushEnabled(true);
+conf.setOutputBufferSize(0);
+conf.setPeriodicFlushFrequencyMilliSeconds(0);
+```
+
+#### Immediate locking
+
+By default, DL writers can write to a log stream when other writers are also writing to that stream. You can override this behavior and disable other writers from writing to the stream by adding this to your configuration:
+
+```java
+conf.setLockTimeout(DistributedLogConstants.LOCK_IMMEDIATE);
+```
+
+#### Writing to logs synchronously
+
+To write records to a log synchronously, you need to instantiate a `LogWriter` object using a `DistributedLogManager`. Here's an example:
+
+```java
+DistributedLogNamespace namespace = /* Some namespace object */;
+DistributedLogManager logManager = namespace.openLog("test-log");
+LogWriter writer = logManager.startLogSegmentNonPartitioned();
+```
+
+> The DistributedLog library enforces single-writer semantics by deploying a ZooKeeper locking mechanism. If there is only one active writer, subsequent calls to `startLogSegmentNonPartitioned` will fail with an `OwnershipAcquireFailedException`.
+
+Log records represent the data written to a log stream. Each log record is associated with an application-defined [TransactionID](#log-records). This ID must be non decreasing or else writing a record will be rejected with `TransactionIdOutOfOrderException`. The application is allowed to bypass the TransactionID sanity checking by setting `maxIdSanityCheck` to `false` in the configuration. System time and atomic numbers are good candidates for TransactionID.
+
+```java
+long txid = 1L;
+byte[] data = "some byte array".getBytes();
+LogRecord record = new LogRecord(txid, data);
+```
+
+Your application can write either a single record, using the `write` method, or many records, using the `writeBulk` method.
+
+```java
+// Single record
+writer.write(record);
+
+// Bulk write
+List<LogRecord> records = Lists.newArrayList();
+records.add(record);
+writer.writeBulk(records);
+```
+
+The write calls return immediately after the records are added into the output buffer of writer. This means that the data isn't guaranteed to be durable until the writer explicitly calls `setReadyToFlush` and `flushAndSync`. Those two calls will first transmit buffered data to the backend, wait for transmit acknowledgements (acks), and commit the written data to make them visible to readers.
+
+```java
+// Flush the records
+writer.setReadyToFlush();
+
+// Commit the records to make them visible to readers
+writer.flushAndSync();
+```
+
+Log streams in DistributedLog are endless streams *unless they are sealed*. Endless in this case means that writers can keep writing records to those streams, readers can keep reading from the end of those streams, and the process never stops. Your application can seal a log stream using the `markEndOfStream` method:
+
+```java
+writer.markEndOfStream();
+```
+
+#### Writing to logs asynchronously
+
+In order to write to DistributedLog logs asynchronously, you need to create an `AsyncLogWriter` instread of a `LogWriter`.
+
+```java
+DistributedLogNamespace namespace = /* Some namespace object */;
+DistributedLogManager logManager = namespace.openLog("test-async-log");
+AsyncLogWriter asyncWriter = logManager.startAsyncLogSegmentNonPartitioned();
+```
+
+All writes to `AsyncLogWriter` are non partitioned. The futures representing write results are only satisfied when the data is durably persisted in the stream. A [DLSN](#log-records) will be returned for each write, which is used to represent the position (aka offset) of the record in the log stream. All the records added in order are guaranteed to be persisted in order. Here's an example of an async writer that gathers a list of futures representing multiple async write results:
+
+```java
+List<Future<DLSN>> addFutures = Lists.newArrayList();
+for (long txid = 1L; txid <= 100L; txid++) {
+    byte[] data = /* some byte array */;
+    LogRecord record = new LogRecord(txid, data);
+    addFutures.add(asyncWriter.write(record));
+}
+List<DLSN> addResults = Await.result(Future.collect(addFutures));
+```
+
+The `AsyncLogWriter` also provides a method for truncating a stream to a given DLSN. This is useful for building replicated state machines that need explicit controls on when the data can be deleted.
+
+```java
+DLSN truncateDLSN = /* some DLSN */;
+Future<DLSN> truncateFuture = asyncWriter.truncate(truncateDLSN);
+
+// Wait for truncation result
+Await.result(truncateFuture);
+```
+
+##### Register a listener
+
+Instead of returning a future from write operations, you can also set up a listener that performs assigned actions upon success or failure of the write. Here's an example:
+
+```java
+asyncWriter.addEventListener(new FutureEventListener<DLSN>() {
+    @Override
+    public void onFailure(Throwable cause) {
+        // Execute if the attempt fails
+    }
+
+    @Override
+    public void onSuccess(DLSN value) {
+        // Execute if the attempt succeeds
+    }
+});
+```
+
+##### Close the writer
+
+You can close an async writer when you're finished with it like this:
+
+```java
+FutureUtils.result(asyncWriter.asyncClose());
+```

+
+<p>A few notes when using this API:</p>
+
+<ul>
+  <li>The entry id has to be non-negative.</li>
+  <li>Clients are okay to add entries out of order.</li>

+
+<h2 id="the-java-ledger-api-client">The Java ledger API client</h2>
+
+<p>To get started with the Java client for BookKeeper, install the <code class="highlighter-rouge">bookkeeper-server</code> library as a dependency in your Java application.</p>
+
+<blockquote>
+  <p>For a more in-depth tutorial that involves a real use case for BookKeeper, see the <a href="#example-application">Example application</a> guide.</p>
+</blockquote>
+
+<h2 id="installation">Installation</h2>
+
+<p>The BookKeeper Java client library is available via <a href="http://search.maven.org/">Maven Central</a> and can be installed using <a href="#maven">Maven</a>, <a href="#gradle">Gradle</a>, and other build tools.</p>
+
+<h3 id="maven">Maven</h3>
+
+<p>If you’re using <a href="https://maven.apache.org/">Maven</a>, add this to your <a href="https://maven.apache.org/guides/introduction/introduction-to-the-pom.html"><code class="highlighter-rouge">pom.xml</code></a> build configuration file:</p>
+
+<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c">&lt;!-- in your &lt;properties&gt; block --&gt;</span>

+<span class="nt">&lt;/dependency&gt;</span>
+</code></pre></div></div>
+
+<p>BookKeeper uses google <a href="https://github.com/google/protobuf/tree/master/java">protobuf</a> and <a href="https://github.com/google/guava">guava</a> libraries
+a lot. If your application might include different versions of protobuf or guava introduced by other dependencies, you can choose to use the
+shaded library, which relocate classes of protobuf and guava into a different namespace to avoid conflicts.</p>

+
+<h3 id="gradle">Gradle</h3>
+
+<p>If you’re using <a href="https://gradle.org/">Gradle</a>, add this to your <a href="https://spring.io/guides/gs/gradle/"><code class="highlighter-rouge">build.gradle</code></a> build configuration file:</p>

+
+<h2 id="connection-string">Connection string</h2>
+
+<p>When interacting with BookKeeper using the Java client, you need to provide your client with a connection string, for which you have three options:</p>
+
+<ul>
+  <li>Provide your entire ZooKeeper connection string, for example <code class="highlighter-rouge">zk1:2181,zk2:2181,zk3:2181</code>.</li>
+  <li>Provide a host and port for one node in your ZooKeeper cluster, for example <code class="highlighter-rouge">zk1:2181</code>. In general, it’s better to provide a full connection string (in case the ZooKeeper node you attempt to connect to is down).</li>
+  <li>If your ZooKeeper cluster can be discovered via DNS, you can provide the DNS name, for example <code class="highlighter-rouge">my-zookeeper-cluster.com</code>.</li>
+</ul>
+
+<h2 id="creating-a-new-client">Creating a new client</h2>
+
+<p>In order to create a new <a href="../javadoc/org/apache/bookkeeper/client/BookKeeper"><code class="highlighter-rouge">BookKeeper</code></a> client object, you need to pass in a <a href="#connection-string">connection string</a>.

+
+<p>There are, however, other ways that you can create a client object:</p>

+
+<p>The easiest way to create a <span class="pop" id="ledger-popover">ledger</span> using the Java client is via the <code class="highlighter-rouge">createLedger</code> method, which creates a new ledger synchronously and returns a <a href="../javadoc/org/apache/bookkeeper/client/LedgerHandle"><code class="highlighter-rouge">LedgerHandle</code></a>. You must specify at least a <a href="../javadoc/org/apache/bookkeeper/client/BookKeeper.DigestType"><code class="highlighter-rouge">DigestType</code></a> and a password.</p>
+
+<p>Here’s an example:</p>
+

+It lets the client read without checking the local value of LastAddConfirmed, so that it is possible to read entries for which the writer has not received the acknowledge yet.
+For entries which are within the range 0..LastAddConfirmed, BookKeeper guarantees that the writer has successfully received the acknowledge.
+For entries outside that range it is possible that the writer never received the acknowledge and so there is the risk that the reader is seeing entries before the writer and this could result in a consistency issue in some cases.
+With this method you can even read entries before the LastAddConfirmed and entries after it with one call, the expected consistency will be as described above.</p>

+
+<h3 id="setup">Setup</h3>
+
+<p>Before you start, you will need to have a BookKeeper cluster running locally on your machine. For installation instructions, see <a href="../../getting-started/installation">Installation</a>.</p>
+
+<p>To start up a cluster consisting of six <span class="pop" id="bookie-popover">bookies</span> locally:</p>

+</ul>
+
+<p>In other words, the log needs to be both durable and consistent, regardless of how many <span class="pop" id="bookie-popover">bookies</span> are participating in the BookKeeper ensemble. If one of the bookies crashes or becomes unable to communicate with the other bookies in any way, it should <em>still</em> display the same sequence of numbers as the others.

+<h3 id="leaders-and-followers-and-a-bit-of-background">Leaders and followers (and a bit of background)</h3>
+
+<p>To achieve this common view in multiple instances of the program, we need each instance to agree on what the next number in the sequence will be. For example, the instances must agree that 4 is the first number and 2 is the second number and 5 is the third number and so on. This is a difficult problem, especially in the case that any instance may go away at any time, and messages between the instances can be lost or reordered.</p>
+
+<p>Luckily, there are already algorithms to solve this. Paxos is an abstract algorithm to implement this kind of agreement, while Zab and Raft are more practical protocols. This video gives a good overview about how these algorithms usually look. They all have a similar core.</p>
+
+<p>It would be possible to run the Paxos to agree on each number in the sequence. However, running Paxos each time can be expensive. What Zab and Raft do is that they use a Paxos-like algorithm to elect a leader. The leader then decides what the sequence of events should be, putting them in a log, which the other instances can then follow to maintain the same state as the leader.</p>
+
+<p>Bookkeeper provides the functionality for the second part of the protocol, allowing a leader to write events to a log and have multiple followers tailing the log. However, bookkeeper does not do leader election. You will need a zookeeper or raft instance for that purpose.</p>
+
+<h3 id="why-not-just-use-zookeeper">Why not just use ZooKeeper?</h3>
+
+<p>There are a number of reasons:</p>
+
+<ol>
+  <li>Zookeeper’s log is only exposed through a tree like interface. It can be hard to shoehorn your application into this.</li>
+  <li>A zookeeper ensemble of multiple machines is limited to one log. You may want one log per resource, which will become expensive very quickly.</li>
+  <li>Adding extra machines to a zookeeper ensemble does not increase capacity nor throughput.</li>
+</ol>
+
+<p>Bookkeeper can be seen as a means of exposing ZooKeeper’s replicated log to applications in a scalable fashion. ZooKeeper is still used by BookKeeper, however, to maintain consistency guarantees, though clients don’t need to interact with ZooKeeper directly.</p>
+
+<h3 id="electing-a-leader">Electing a leader</h3>
+
+<p>We’ll use zookeeper to elect a leader. A zookeeper instance will have started locally when you started the localbookie application above. To verify it’s running, run the following command.</p>

+<p>To interact with zookeeper, we’ll use the Curator client rather than the stock zookeeper client. Getting things right with the zookeeper client can be tricky, and curator removes a lot of the pointy corners for you. In fact, curator even provides a leader election recipe, so we need to do very little work to get leader election in our application.</p>

+
+<p>In the constructor for Dice, we need to create the curator client. We specify four things when creating the client, the location of the zookeeper service, the session timeout, the connect timeout and the retry policy.</p>
+
+<p>The session timeout is a zookeeper concept. If the zookeeper server doesn’t hear anything from the client for this amount of time, any leases which the client holds will be timed out. This is important in leader election. For leader election, the curator client will take a lease on ELECTION_PATH. The first instance to take the lease will become leader and the rest will become followers. However, their claim on the lease will remain in the cue. If the first instance then goes away, due to a crash etc., its session will timeout. Once the session times out, the lease will be released and the next instance in the queue will become the leader. The call to autoRequeue() will make the client queue itself again if it loses the lease for some other reason, such as if it was still alive, but it a garbage collection cycle caused it to lose its session, and thereby its lease. I’ve set the lease to be quite low so that when we test out leader election, transitions will be quite quick. The optimum length for session timeout depends very much on the use case. The other parameters are the connection timeout, i.e. the amount of time it will spend trying to connect to a zookeeper server before giving up, and the retry policy. The retry policy specifies how the client should respond to transient errors, such as connection loss. Operations that fail with transient errors can be retried, and this argument specifies how often the retries should occur.</p>
+
+<p>Finally, you’ll have noticed that Dice now extends LeaderSelectorListenerAdapter and implements Closeable. Closeable is there to close the resource we have initialized in the constructor, the curator client and the leaderSelector. LeaderSelectorListenerAdapter is a callback that the leaderSelector uses to notify the instance that it is now the leader. It is passed as the third argument to the LeaderSelector constructor.</p>

+<p>takeLeadership() is the callback called by LeaderSelector when the instance is leader. It should only return when the instance wants to give up leadership. In our case, we never do so we wait on the current object until we’re interrupted. To signal to the rest of the program that we are leader we set a volatile boolean called leader to true. This is unset after we are interrupted.</p>

+
+<p>In BookKeeper by default each write will be acklowledged to the client if and only if it has been persisted durably (fsync called on the file system) by a quorum of bookies.
+In this case the LastAddConfirmed pointer is updated on the writer side, this is the guarantee for the writer that data will not be lost and it will
+be always readable by other clients.</p>
+
+<p>On the client side you can temporary relax this constraint by using the <a href="../javadoc/org/apache/bookkeeper/client/api/WriteFlag"><code class="highlighter-rouge">DEFERRED_SYNC</code></a> Write flag. Using this flag bookies will acknowledge each entry after
+writing the entry to SO buffers without waiting for an fsync.
+In this case the LastAddConfirmed pointer is not advanced to the writer side neither is updated on the reader’s side, this is because <strong>there is some chance to lose the entry</strong>.
+Such entries will be still readable using readUnconfirmed() API, but they won’t be readable using Long Poll reads or regular read() API.</p>
+
+<p>In order to get guarantees of durability the writer must use explicitly the <a href="../javadoc/org/apache/bookkeeper/client/api/ForceableHandle">force()</a> API which will return only after all the bookies in the ensemble acknowledge the call after
+performing an fsync to the disk which is storing the journal.
+This way the LastAddConfirmed pointer is advanced on the writer side and it will be eventually available to the readers.</p>
+
+<p>The <em>close()</em> operation on the writer writes on ledger’s metadata the current LastAddConfirmed pointer, <strong>it is up to the application to call force() before issuing the close command</strong>.
+In case that you never call explicitly <a href="../javadoc/org/apache/bookkeeper/client/api/ForceableHandle">force()</a> the LastAddConfirmed will remain unset (-1) on ledger metadata and regular readers won’t be able to access data.</p>

+          <p>BookKeeper offers a few APIs that applications can use to interact with it:</p>
+
+<ul>
+  <li>The <a href="../ledger-api">ledger API</a> is a lower-level API that enables you to interact with <span class="pop" id="ledger-popover">ledgers</span> directly</li>
+  <li>The <a href="../ledger-adv-api">Ledger Advanced API</a> is an advanced extension to <a href="../ledger-api">Ledger API</a> to provide more flexibilities to applications.</li>
+  <li>The <a href="../distributedlog-api">DistributedLog API</a> is a higher-level API that provides convenient abstractions.</li>
+</ul>
+
+<h2 id="trade-offs">Trade-offs</h2>
+
+<p>The <code class="highlighter-rouge">Ledger API</code> provides direct access to ledgers and thus enables you to use BookKeeper however you’d like.</p>
+
+<p>However, in most of use cases, if you want a <code class="highlighter-rouge">log stream</code>-like abstraction, it requires you to manage things like tracking list of ledgers,
+managing rolling ledgers and data retention on your own. In such cases, you are recommended to use <a href="../distributedlog-api">DistributedLog API</a>,
+with semantics resembling continous log streams from the standpoint of applications.</p>

+          <p><a href="https://dcos.io/">DC/OS</a> (the <strong>D</strong>ata<strong>C</strong>enter <strong>O</strong>perating <strong>S</strong>ystem) is a distributed operating system used for deploying and managing applications and systems on <a href="http://mesos.apache.org/">Apache Mesos</a>. DC/OS is an open-source tool created and maintained by <a href="https://mesosphere.com/">Mesosphere</a>.</p>
+
+<p>BookKeeper is available as a <a href="http://universe.dcos.io/#/package/bookkeeper/version/latest">DC/OS package</a> from the <a href="http://universe.dcos.io/#/packages">Mesosphere DC/OS Universe</a>.</p>
+
+<h2 id="prerequisites">Prerequisites</h2>
+
+<p>In order to run BookKeeper on DC/OS, you will need:</p>
+
+<ul>
+  <li>DC/OS version <a href="https://dcos.io/docs/1.8/">1.8</a> or higher</li>
+  <li>A DC/OS cluster with at least three nodes</li>
+  <li>The <a href="https://dcos.io/docs/1.8/usage/cli/install/">DC/OS CLI tool</a> installed</li>
+</ul>
+
+<p>Each node in your DC/OS-managed Mesos cluster must have at least:</p>
+
+<ul>
+  <li>1 CPU</li>
+  <li>1 GB of memory</li>
+  <li>10 GB of total persistent disk storage</li>
+</ul>

+<h2 id="installing-bookkeeper">Installing BookKeeper</h2>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>dcos package <span class="nb">install </span>bookkeeper <span class="nt">--yes</span>
+</code></pre></div></div>
+
+<p>This command will:</p>
+
+<ul>
+  <li>Install the <code class="highlighter-rouge">bookkeeper</code> subcommand for the <code class="highlighter-rouge">dcos</code> CLI tool</li>
+  <li>Start a single <span class="pop" id="bookie-popover">bookie</span> on the Mesos cluster with the <a href="../../reference/config">default configuration</a></li>
+</ul>
+
+<p>The bookie that is automatically started up uses the host mode of the network and by default exports the service at <code class="highlighter-rouge">agent_ip:3181</code>.</p>
+
+<blockquote>
+  <p>If you run <code class="highlighter-rouge">dcos package install bookkeeper</code> without setting the <code class="highlighter-rouge">--yes</code> flag, the install will run in interactive mode. For more information on the <code class="highlighter-rouge"><span class="k">package</span> <span class="n">install</span></code> command, see the <a href="https://docs.mesosphere.com/latest/cli/command-reference/dcos-package/dcos-package-install/">DC/OS docs</a>.</p>
+</blockquote>
+
+<h3 id="services">Services</h3>
+
+<p>To watch BookKeeper start up, click on the <strong>Services</strong> tab in the DC/OS <a href="https://docs.mesosphere.com/latest/gui/">user interface</a> and you should see the <code class="highlighter-rouge">bookkeeper</code> package listed:</p>
+
+<p><img src="/img/dcos/services.png" alt="DC/OS services" /></p>
+
+<h3 id="tasks">Tasks</h3>
+
+<p>To see which tasks have started, click on the <code class="highlighter-rouge">bookkeeper</code> service and you’ll see an interface that looks like this;</p>
+
+<p><img src="/img/dcos/tasks.png" alt="DC/OS tasks" /></p>
+
+<h2 id="scaling-bookkeeper">Scaling BookKeeper</h2>
+
+<p>Once the first <span class="pop" id="bookie-popover">bookie</span> has started up, you can click on the <strong>Scale</strong> tab to scale up your BookKeeper ensemble by adding more bookies (or scale down the ensemble by removing bookies).</p>
+
+<p><img src="/img/dcos/scale.png" alt="DC/OS scale" /></p>
+
+<h2 id="zookeeper-exhibitor">ZooKeeper Exhibitor</h2>
+
+<p>ZooKeeper contains the information for all bookies in the ensemble. When deployed on DC/OS, BookKeeper uses a ZooKeeper instance provided by DC/OS. You can access a visual UI for ZooKeeper using <a href="https://github.com/soabase/exhibitor/wiki">Exhibitor</a>, which is available at <a href="http://master.dcos/exhibitor">http://master.dcos/exhibitor</a>.</p>
+
+<p><img src="/img/dcos/exhibitor.png" alt="ZooKeeper Exhibitor" /></p>
+
+<p>You should see a listing of IP/host information for all bookies under the <code class="highlighter-rouge">messaging/bookkeeper/ledgers/available</code> node.</p>
+
+<h2 id="client-connections">Client connections</h2>
+
+<p>To connect to bookies running on DC/OS using clients running within your Mesos cluster, you need to specify the ZooKeeper connection string for DC/OS’s ZooKeeper cluster:</p>
+
+<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>master.mesos:2181
+</code></pre></div></div>
+
+<p>This is the <em>only</em> ZooKeeper host/port you need to include in your connection string. Here’s an example using the <a href="../../api/ledger-api#the-java-ledger-api-client">Java client</a>:</p>
+
+<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">BookKeeper</span> <span class="n">bkClient</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">BookKeeper</span><span class="o">(</span><span class="s">"master.mesos:2181"</span><span class="o">);</span>
+</code></pre></div></div>
+
+<p>If you’re connecting using a client running outside your Mesos cluster, you need to supply the public-facing connection string for your DC/OS ZooKeeper cluster.</p>
+
+<h2 id="configuring-bookkeeper">Configuring BookKeeper</h2>
+
+<p>By default, the <code class="highlighter-rouge">bookkeeper</code> package will start up a BookKeeper ensemble consisting of one <span class="pop" id="bookie-popover">bookie</span> with one CPU, 1 GB of memory, and a 70 MB persistent volume.</p>
+
+<p>You can supply a non-default configuration when installing the package using a JSON file. Here’s an example command:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>dcos package <span class="nb">install </span>bookkeeper <span class="se">\</span>
+  <span class="nt">--options</span><span class="o">=</span>/path/to/config.json
+</code></pre></div></div>
+
+<p>You can then fetch the current configuration for BookKeeper at any time using the <code class="highlighter-rouge"><span class="k">package</span> <span class="n">describe</span></code> command:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>dcos package describe bookkeeper <span class="se">\</span>
+  <span class="nt">--config</span>

+          <p>Apache BookKeeper can be easily deployed in <a href="https://kubernetes.io/">Kubernetes</a> clusters. The managed clusters on <a href="https://cloud.google.com/compute/">Google Container Engine</a> is the most convenient way.</p>
+
+<p>The deployment method shown in this guide relies on <a href="http://yaml.org/">YAML</a> definitions for Kubernetes <a href="https://kubernetes.io/docs/resources-reference/v1.6/">resources</a>. The <a href="https://github.com/apache/bookkeeper/tree/master/deploy/kubernetes"><code class="highlighter-rouge">kubernetes</code></a> subdirectory holds resource definitions for:</p>
+
+<ul>
+  <li>A three-node ZooKeeper cluster</li>
+  <li>A BookKeeper cluster with a bookie runs on each node.</li>
+</ul>
+
+<h2 id="setup-on-google-container-engine">Setup on Google Container Engine</h2>
+
+<p>To get started, get source code of <a href="https://github.com/apache/bookkeeper/tree/master/deploy/kubernetes"><code class="highlighter-rouge">kubernetes</code></a> from github by git clone.</p>
+
+<p>If you’d like to change the number of bookies,  or ZooKeeper nodes in your BookKeeper cluster, modify the <code class="highlighter-rouge">replicas</code> parameter in the <code class="highlighter-rouge">spec</code> section of the appropriate <a href="https://kubernetes.io/docs/concepts/workloads/controllers/deployment/"><code class="highlighter-rouge">Deployment</code></a> or <a href="https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/"><code class="highlighter-rouge">StatefulSet</code></a> resource.</p>
+
+<p><a href="https://cloud.google.com/container-engine">Google Container Engine</a> (GKE) automates the creation and management of Kubernetes clusters in <a href="https://cloud.google.com/compute/">Google Compute Engine</a> (GCE).</p>
+
+<h3 id="prerequisites">Prerequisites</h3>
+
+<p>To get started, you’ll need:</p>
+
+<ul>
+  <li>A Google Cloud Platform account, which you can sign up for at <a href="https://cloud.google.com">cloud.google.com</a></li>
+  <li>An existing Cloud Platform project</li>
+  <li>The <a href="https://cloud.google.com/sdk/downloads">Google Cloud SDK</a> (in particular the <a href="https://cloud.google.com/sdk/gcloud/"><code class="highlighter-rouge">gcloud</code></a> and <a href=""><code class="highlighter-rouge">kubectl</code></a> tools).</li>
+</ul>
+
+<h3 id="create-a-new-kubernetes-cluster">Create a new Kubernetes cluster</h3>
+
+<p>You can create a new GKE cluster using the <a href="https://cloud.google.com/sdk/gcloud/reference/container/clusters/create"><code class="highlighter-rouge">container clusters create</code></a> command for <code class="highlighter-rouge">gcloud</code>. This command enables you to specify the number of nodes in the cluster, the machine types of those nodes, and more.</p>
+
+<p>As an example, we’ll create a new GKE cluster for Kubernetes version <a href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG.md#v164">1.6.4</a> in the <a href="https://cloud.google.com/compute/docs/regions-zones/regions-zones#available">us-central1-a</a> zone. The cluster will be named <code class="highlighter-rouge">bookkeeper-gke-cluster</code> and will consist of three VMs, each using two locally attached SSDs and running on <a href="https://cloud.google.com/compute/docs/machine-types">n1-standard-8</a> machines. These SSDs will be used by Bookie instances, one for the BookKeeper journal and the other for storing the actual data.</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>gcloud config <span class="nb">set </span>compute/zone us-central1-a
+<span class="nv">$ </span>gcloud config <span class="nb">set </span>project your-project-name
+<span class="nv">$ </span>gcloud container clusters create bookkeeper-gke-cluster <span class="se">\</span>
+  <span class="nt">--machine-type</span><span class="o">=</span>n1-standard-8 <span class="se">\</span>
+  <span class="nt">--num-nodes</span><span class="o">=</span>3 <span class="se">\</span>
+  <span class="nt">--local-ssd-count</span><span class="o">=</span>2 <span class="se">\</span>
+  <span class="nt">--enable-kubernetes-alpha</span>
+</code></pre></div></div>
+
+<p>By default, bookies will run on all the machines that have locally attached SSD disks. In this example, all of those machines will have two SSDs, but you can add different types of machines to the cluster later. You can control which machines host bookie servers using <a href="https://kubernetes.io/docs/concepts/overview/working-with-objects/labels">labels</a>.</p>
+
+<h3 id="dashboard">Dashboard</h3>
+
+<p>You can observe your cluster in the <a href="https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/">Kubernetes Dashboard</a> by downloading the credentials for your Kubernetes cluster and opening up a proxy to the cluster:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>gcloud container clusters get-credentials bookkeeper-gke-cluster <span class="se">\</span>
+  <span class="nt">--zone</span><span class="o">=</span>us-central1-a <span class="se">\</span>
+  <span class="nt">--project</span><span class="o">=</span>your-project-name
+<span class="nv">$ </span>kubectl proxy
+</code></pre></div></div>
+
+<p>By default, the proxy will be opened on port 8001. Now you can navigate to <a href="http://localhost:8001/ui">localhost:8001/ui</a> in your browser to access the dashboard. At first your GKE cluster will be empty, but that will change as you begin deploying.</p>
+
+<p>When you create a cluster, your <code class="highlighter-rouge">kubectl</code> config in <code class="highlighter-rouge">~/.kube/config</code> (on MacOS and Linux) will be updated for you, so you probably won’t need to change your configuration. Nonetheless, you can ensure that <code class="highlighter-rouge">kubectl</code> can interact with your cluster by listing the nodes in the cluster:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>kubectl get nodes
+</code></pre></div></div>
+
+<p>If <code class="highlighter-rouge">kubectl</code> is working with your cluster, you can proceed to deploy ZooKeeper and Bookies.</p>
+
+<h3 id="zookeeper">ZooKeeper</h3>
+
+<p>You <em>must</em> deploy ZooKeeper as the first component, as it is a dependency for the others.</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>kubectl apply <span class="nt">-f</span> zookeeper.yaml
+</code></pre></div></div>
+
+<p>Wait until all three ZooKeeper server pods are up and have the status <code class="highlighter-rouge">Running</code>. You can check on the status of the ZooKeeper pods at any time:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>kubectl get pods <span class="nt">-l</span> <span class="nv">component</span><span class="o">=</span>zookeeper
+NAME      READY     STATUS             RESTARTS   AGE
+zk-0      1/1       Running            0          18m
+zk-1      1/1       Running            0          17m
+zk-2      0/1       Running            6          15m
+</code></pre></div></div>
+
+<p>This step may take several minutes, as Kubernetes needs to download the Docker image on the VMs.</p>
+
+<p>If you want to connect to one of the remote zookeeper server, you can use<a href="https://github.com/rgs1/zk_shell">zk-shell</a>, you need to forward a local port to the
+remote zookeeper server:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>kubectl port-forward zk-0 2181:2181
+<span class="nv">$ </span>zk-shell localhost 2181
+</code></pre></div></div>
+
+<h3 id="deploy-bookies">Deploy Bookies</h3>

+<p>Once ZooKeeper cluster is Running, you can then deploy the bookies. You can deploy the bookies either using a <a href="https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/">DaemonSet</a> or a <a href="https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/">StatefulSet</a>.</p>
+
+<blockquote>
+  <p>NOTE: <em>DaemonSet</em> vs <em>StatefulSet</em></p>
+
+  <p>A <em>DaemonSet</em> ensures that all (or some) nodes run a pod of bookie instance. As nodes are added to the cluster, bookie pods are added automatically to them. As nodes are removed from the
+cluster, those bookie pods are garbage collected. The bookies deployed in a DaemonSet stores data on the local disks on those nodes. So it doesn’t require any external storage for Persistent
+Volumes.</p>
+
+  <p>A <em>StatefulSet</em> maintains a sticky identity for the pods that it runs and manages. It provides stable and unique network identifiers, and stable and persistent storage for each pod. The pods
+are not interchangeable, the idenifiers for each pod are maintained across any rescheduling.</p>
+
+  <p>Which one to use? A <em>DaemonSet</em> is the easiest way to deploy a bookkeeper cluster, because it doesn’t require additional persistent volume provisioner and use local disks. BookKeeper manages
+the data replication. It maintains the best latency property. However, it uses <code class="highlighter-rouge">hostIP</code> and <code class="highlighter-rouge">hostPort</code> for communications between pods. In some k8s platform (such as DC/OS), <code class="highlighter-rouge">hostIP</code> and
+<code class="highlighter-rouge">hostPort</code> are not well supported. A <em>StatefulSet</em> is only practical when deploying in a cloud environment or any K8S installation that has persistent volumes available. Also be aware, latency
+can be potentially higher when using persistent volumes, because there is usually built-in replication in the persistent volumes.</p>

+          <p>The easiest way to deploy BookKeeper is using schedulers like <a href="../dcos">DC/OS</a>, but you can also deploy BookKeeper clusters manually. A BookKeeper cluster consists of two main components:</p>
+
+<ul>
+  <li>A <a href="#zookeeper-setup">ZooKeeper</a> cluster that is used for configuration- and coordination-related tasks</li>
+  <li>An <a href="#starting-up-bookies">ensemble</a> of <span class="pop" id="bookie-popover">bookies</span></li>
+</ul>
+
+<h2 id="zookeeper-setup">ZooKeeper setup</h2>
+
+<p>We won’t provide a full guide to setting up a ZooKeeper cluster here. We recommend that you consult <a href="https://zookeeper.apache.org/doc/current/zookeeperAdmin.html">this guide</a> in the official ZooKeeper documentation.</p>
+
+<h2 id="cluster-metadata-setup">Cluster metadata setup</h2>
+
+<p>Once your ZooKeeper cluster is up and running, there is some metadata that needs to be written to ZooKeeper, so you need to modify the bookie’s configuration to make sure that it points to the right ZooKeeper cluster.</p>
+
+<p>On each bookie host, you need to <a href="../../getting-started/installation#download">download</a> the BookKeeper package as a tarball. Once you’ve done that, you need to configure the bookie by setting values in the <code class="highlighter-rouge">bookkeeper-server/conf/bk_server.conf</code> config file. The one parameter that you will absolutely need to change is the <a href="../../config#zkServers"><code class="highlighter-rouge">zkServers</code></a> parameter, which you will need to set to the ZooKeeper connection string for your ZooKeeper cluster. Here’s an example:</p>
+
+<div class="language-properties highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="py">zkServers</span><span class="p">=</span><span class="s">100.0.0.1:2181,100.0.0.2:2181,100.0.0.3:2181</span>
+</code></pre></div></div>
+
+<blockquote>
+  <p>A full listing of configurable parameters available in <code class="highlighter-rouge">bookkeeper-server/conf/bk_server.conf</code> can be found in the <a href="../../reference/config">Configuration</a> reference manual.</p>
+</blockquote>
+
+<p>Once the bookie’s configuration is set, you can set up cluster metadata for the cluster by running the following command from any bookie in the cluster:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell metaformat
+</code></pre></div></div>
+
+<p>You can run in the formatting</p>
+
+<blockquote>
+  <p>The <code class="highlighter-rouge">metaformat</code> command performs all the necessary ZooKeeper cluster metadata tasks and thus only needs to be run <em>once</em> and from <em>any</em> bookie in the BookKeeper cluster.</p>
+</blockquote>
+
+<p>Once cluster metadata formatting has been completed, your BookKeeper cluster is ready to go!</p>
+
+<h2 id="starting-up-bookies">Starting up bookies</h2>
+
+<p>Before you start up your bookies, you should make sure that all bookie hosts have the correct configuration, then you can start up as many <span class="pop" id="bookie-popover">bookies</span> as you’d like to form a cluster by using the <a href="../../reference/cli#bookkeeper-bookie"><code class="highlighter-rouge">bookie</code></a> command of the <a href="../../reference/cli#bookkeeper"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper bookie
+</code></pre></div></div>
+
+<h3 id="system-requirements">System requirements</h3>
+
+<p>The number of bookies you should run in a BookKeeper cluster depends on the quorum mode that you’ve chosen, the desired throughput, and the number of clients using the cluster simultaneously.</p>
+
+<table>
+  <thead>
+    <tr>
+      <th style="text-align: left">Quorum type</th>
+      <th style="text-align: left">Number of bookies</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td style="text-align: left">Self-verifying quorum</td>
+      <td style="text-align: left">3</td>
+    </tr>
+    <tr>
+      <td style="text-align: left">Generic</td>
+      <td style="text-align: left">4</td>
+    </tr>
+  </tbody>
+</table>
+
+<p>Increasing the number of bookies will enable higher throughput, and there is <strong>no upper limit</strong> on the number of bookies.</p>

+
+<h2 id="ledgers">Ledgers</h2>
+
+<p><span class="pop" id="ledger-popover">Ledgers</span> are the basic building block of BookKeeper and the level at which BookKeeper makes its persistent storage guarantees. A replicated log consists of an ordered list of ledgers. See <a href="#ledgers-to-logs">Ledgers to logs</a> for info on building a replicated log from ledgers.</p>
+
+<p>Ledgers are composed of metadata and <span class="pop" id="entry-popover">entries</span>. The metadata is stored in ZooKeeper, which provides a <em>compare-and-swap</em> (CAS) operation. Entries are stored on storage nodes known as <span class="pop" id="bookie-popover">bookies</span>.</p>
+
+<p>A ledger has a single writer and multiple readers (SWMR).</p>
+
+<h3 id="ledger-metadata">Ledger metadata</h3>
+
+<p>A ledger’s metadata contains the following:</p>
+
+<table>
+  <thead>
+    <tr>
+      <th style="text-align: left">Parameter</th>
+      <th style="text-align: left">Name</th>

+      <td style="text-align: left"><strong>Q<sub>a</sub></strong></td>

+    </tr>
+  </tbody>
+</table>
+
+<p>In addition, each ledger’s metadata consists of one or more <em>fragments</em>. Each fragment is either</p>
+
+<ul>
+  <li>the first entry of a fragment or</li>
+  <li>a list of bookies for the fragment.</li>
+</ul>
+
+<p>When creating a ledger, the following invariant must hold:</p>
+
+<p><strong>E &gt;= Q<sub>w</sub> &gt;= Qa</strong></p>
+
+<p>Thus, the ensemble size (<strong>E</strong>) must be larger than the write quorum size (<strong>Q<sub>w</sub></strong>), which must in turn be larger than the ack quorum size (<strong>Q<sub>a</sub></strong>). If that condition does not hold, then the ledger creation operation will fail.</p>
+
+<h3 id="ensembles">Ensembles</h3>
+
+<p>When a ledger is created, <strong>E</strong> bookies are chosen for the entries of that ledger. The bookies are the initial ensemble of the ledger. A ledger can have multiple ensembles, but an entry has only one ensemble. Changes in the ensemble involve a new fragment being added to the ledger.</p>
+
+<p>Take the following example. In this ledger, with ensemble size of 3, there are two fragments and thus two ensembles, one starting at entry 0, the second at entry 12. The second ensemble differs from the first only by its first element. This could be because bookie1 has failed and therefore had to be replaced.</p>

+
+<h3 id="write-quorums">Write quorums</h3>
+
+<p>Each entry in the log is written to <strong>Q<sub>w</sub></strong> nodes. This is considered the write quorum for that entry. The write quorum is the subsequence of the ensemble, <strong>Q<sub>w</sub></strong> in length, and starting at the bookie at index (entryid % <strong>E</strong>).</p>
+
+<p>For example, in a ledger of <strong>E</strong> = 4, <strong>Q<sub>w</sub></strong> = 3, and <strong>Q<sub>a</sub></strong> = 2, with an ensemble consisting of B1, B2, B3, and B4, the write quorums for the first 6 entries will be:</p>

+
+<p>There are only <strong>E</strong> distinct write quorums in any ensemble. If <strong>Q<sub>w</sub></strong> = <strong>Q<sub>a</sub></strong>, then there is only one, as no striping occurs.</p>
+
+<h3 id="ack-quorums">Ack quorums</h3>
+
+<p>The ack quorum for an entry is any subset of the write quorum of size <strong>Q<sub>a</sub></strong>. If <strong>Q<sub>a</sub></strong> bookies acknowledge an entry, it means it has been fully replicated.</p>
+
+<h3 id="guarantees">Guarantees</h3>
+
+<p>The system can tolerate <strong>Q<sub>a</sub></strong> – 1 failures without data loss.</p>
+
+<p>Bookkeeper guarantees that:</p>
+
+<ol>
+  <li>All updates to a ledger will be read in the same order as they were written.</li>
+  <li>All clients will read the same sequence of updates from the ledger.</li>
+</ol>
+
+<h2 id="writing-to-ledgers">Writing to ledgers</h2>
+
+<p>writer, ensuring that entry ids are sequential is trivial. A bookie acknowledges a write once it has been persisted to disk and is therefore durable. Once <strong>Q<sub>a</sub></strong> bookies from the write quorum acknowledge the write, the write is acknowledged to the client, but only if all entries with lower entry ids in the ledger have already been acknowledged to the client.</p>
+
+<p>The entry written contains the ledger id, the entry id, the last add confirmed and the payload. The last add confirmed is the last entry which had been acknowledged to the client when this entry was written. Sending this with the entry speeds up recovery of the ledger in the case that the writer crashes.</p>
+
+<p>Another client can also read entries in the ledger up as far as the last add confirmed, as we guarantee that all entries thus far have been replicated on Qa nodes, and therefore all future readers will be able to also read it. However, to read like this, the ledger should be opened with a non-fencing open. Otherwise, it would kill the writer.</p>
+
+<p>If a node fails to acknowledge a write, the writer will create a new ensemble by replacing the failed node in the current ensemble. It creates a new fragment with this ensemble, starting from the first message that has not been acknowledged to the client. Creating the new fragment involves making a CAS write to the metadata. If the CAS write fails, someone else has modified something in the ledger metadata. This concurrent modification could have been caused by recovery or <span class="pop" id="rereplication-popover">rereplication</span>. We reread the metadata. If the state of the ledger is no longer <code class="highlighter-rouge">OPEN</code>, we send an error to the client for any outstanding writes. Otherwise, we try to replace the failed node again.</p>
+
+<h3 id="closing-a-ledger-as-a-writer">Closing a ledger as a writer</h3>
+
+<p>Closing a ledger is straightforward for a writer. The writer makes a CAS write to the metadata, changing the state to <code class="highlighter-rouge">CLOSED</code> and setting the last entry of the ledger to the last entry which we have acknowledged to the client.</p>
+
+<p>If the CAS write fails, it means someone else has modified the metadata. We reread the metadata, and retry closing as long as the state of the ledger is still <code class="highlighter-rouge">OPEN</code>. If the state is <code class="highlighter-rouge">IN_RECOVERY</code> we send an error to the client. If the state is <code class="highlighter-rouge">CLOSED</code> and the last entry is the same as the last entry we have acknowledged to the client, we complete the close operation successfully. If the last entry is different from what we have acknowledged to the client, we send an error to the client.</p>
+
+<h3 id="closing-a-ledger-as-a-reader">Closing a ledger as a reader</h3>
+
+<p>A reader can also force a ledger to close. Forcing the ledger to close will prevent any writer from adding new entries to the ledger. This is called <span class="pop" id="fencing-popover">fencing</span>. This can occur when a writer has crashed or become unavailable, and a new writer wants to take over writing to the log. The new writer must ensure that it has seen all updates from the previous writer, and prevent the previous writer from making any new updates before making any updates of its own.</p>
+
+<p>To recover a ledger, we first update the state in the metadata to IN_RECOVERY. We then send a fence message to all the bookies in the last fragment of the ledger. When a bookie receives a fence message for a ledger, the fenced state of the ledger is persisted to disk. Once we receive a response from at least (<strong>Q<sub>w</sub></strong> - <strong>Q<sub>a</sub></strong>)+1 bookies from each write quorum in the ensemble, the ledger is fenced.</p>
+
+<p>By ensuring we have received a response from at last (<strong>Q<sub>w</sub></strong> - <strong>Q<sub>a</sub></strong>) + 1 bookies in each write quorum, we ensure that, if the old writer is alive and tries to add a new entry there will be no write quorum in which Qa bookies will accept the write. If the old writer tries to update the ensemble, it will fail on the CAS metadata write, and then see that the ledger is in IN_RECOVERY state, and that it therefore shouldn’t try to write to it.</p>
+
+<p>The old writer will be able to write entries to individual bookies (we can’t guarantee that the fence message reaches all bookies), but as it will not be able reach ack quorum, it will not be able to send a success response to its client. The client will get a LedgerFenced error instead.</p>
+
+<p>It is important to note that when you get a ledger fenced message for an entry, it doesn’t mean that the entry has not been written. It means that the entry may or may not have been written, and this can only be determined after the ledger is recovered. In effect, LedgerFenced should be treated like a timeout.</p>
+
+<p>Once the ledger is fenced, recovery can begin. Recovery means finding the last entry of the ledger and closing the ledger. To find the last entry of the ledger, the client asks all bookies for the highest last add confirmed value they have seen. It waits until it has received a response at least (<strong>Q<sub>w</sub></strong> - <strong>Q<sub>a</sub></strong>) + 1 bookies from each write quorum, and takes the highest response as the entry id to start reading forward from. It then starts reading forward in the ledger, one entry at a time, replicating all entries it sees to the entire write quorum for that entry. Once it can no longer read any more entries, it updates the state in the metadata to <code class="highlighter-rouge">CLOSED</code>, and sets the last entry of the ledger to the last entry it wrote. Multiple readers can try to recovery a ledger at the same time, but as the metadata write is CAS they will all converge on the same last entry of the ledger.</p>
+
+<h2 id="ledgers-to-logs">Ledgers to logs</h2>
+
+<p>In BookKeeper, <span class="pop" id="ledger-popover">ledgers</span> can be used to build a replicated log for your system. All guarantees provided by BookKeeper are at the ledger level. Guarantees on the whole log can be built using the ledger guarantees and any consistent datastore with a compare-and-swap (CAS) primitive. BookKeeper uses ZooKeeper as the datastore but others could theoretically be used.</p>
+
+<p>A log in BookKeeper is built from some number of ledgers, with a fixed order. A ledger represents a single segment of the log. A ledger could be the whole period that one node was the leader, or there could be multiple ledgers for a single period of leadership. However, there can only ever be one leader that adds entries to a single ledger. Ledgers cannot be reopened for writing once they have been closed/recovered.</p>
+
+<blockquote>
+  <p>BookKeeper does <em>not</em> provide leader election. You must use a system like ZooKeeper for this.</p>
+</blockquote>
+
+<p>In many cases, leader election is really leader suggestion. Multiple nodes could think that they are leader at any one time. It is the job of the log to guarantee that only one can write changes to the system.</p>
+
+<h3 id="opening-a-log">Opening a log</h3>
+
+<p>Once a node thinks it is leader for a particular log, it must take the following steps:</p>
+
+<ol>
+  <li>Read the list of ledgers for the log</li>
+  <li><span class="pop" id="fencing-popover">Fence</span> the last two ledgers in the list. Two ledgers are fenced because the writer may be writing to the second-to-last ledger while adding the last ledger to the list.</li>
+  <li>Create a new ledger</li>
+  <li>Add the new ledger to the ledger list</li>
+  <li>Write the new ledger back to the datastore using a CAS operation</li>
+</ol>
+
+<p>The fencing in step 2 and the CAS operation in step 5 prevent two nodes from thinking that they have leadership at any one time.</p>
+
+<p>The CAS operation will fail if the list of ledgers has changed between reading it and writing back the new list. When the CAS operation fails, the leader must start at step 1 again. Even better, they should check that they are in fact still the leader with the system that is providing leader election. The protocol will work correctly without this step, though it will be able to make very little progress if two nodes think they are leader and are duelling for the log.</p>
+
+<p>The node must not serve any writes until step 5 completes successfully.</p>
+
+<h3 id="rolling-ledgers">Rolling ledgers</h3>
+
+<p>The leader may wish to close the current ledger and open a new one every so often. Ledgers can only be deleted as a whole. If you don’t roll the log, you won’t be able to clean up old entries in the log without a leader change. By closing the current ledger and adding a new one, the leader allows the log to be truncated whenever that data is no longer needed. The steps for rolling the log is similar to those for creating a new ledger.</p>
+
+<ol>
+  <li>Create a new ledger</li>
+  <li>Add the new ledger to the ledger list</li>
+  <li>Write the new ledger list to the datastore using CAS</li>
+  <li>Close the previous ledger</li>
+</ol>
+
+<p>By deferring the closing of the previous ledger until step 4, we can continue writing to the log while we perform metadata update operations to add the new ledger. This is safe as long as you fence the last 2 ledgers when acquiring leadership.</p>

+
+<h2 id="basic-terms">Basic terms</h2>
+
+<p>In BookKeeper:</p>
+
+<ul>
+  <li>each unit of a log is an <a href="#entries"><em>entry</em></a> (aka record)</li>

+  <li>individual servers storing ledgers of entries are called <a href="#bookies"><em>bookies</em></a></li>
+</ul>
+
+<p>BookKeeper is designed to be reliable and resilient to a wide variety of failures. Bookies can crash, corrupt data, or discard data, but as long as there are enough bookies behaving correctly in the ensemble the service as a whole will behave correctly.</p>

+
+<h2 id="ledgers">Ledgers</h2>
+
+<blockquote>
+  <p><strong>Ledgers</strong> are the basic unit of storage in BookKeeper.</p>
+</blockquote>
+
+<p>Ledgers are sequences of entries, while each entry is a sequence of bytes. Entries are written to a ledger:</p>
+
+<ul>
+  <li>sequentially, and</li>
+  <li>at most once.</li>
+</ul>
+
+<p>This means that ledgers have <em>append-only</em> semantics. Entries cannot be modified once they’ve been written to a ledger. Determining the proper write order is the responsibility of <a href="#clients">client applications</a>.</p>
+
+<h2 id="clients-and-apis">Clients and APIs</h2>
+
+<blockquote>
+  <p>BookKeeper clients have two main roles: they create and delete ledgers, and they read entries from and write entries to ledgers.</p>
+
+  <p>BookKeeper provides both a lower-level and a higher-level API for ledger interaction.</p>
+</blockquote>
+
+<p>There are currently two APIs that can be used for interacting with BookKeeper:</p>
+
+<ul>
+  <li>The <a href="../../api/ledger-api">ledger API</a> is a lower-level API that enables you to interact with <span class="pop" id="ledger-popover">ledgers</span> directly.</li>
+  <li>The <a href="../../api/distributedlog-api">DistributedLog API</a> is a higher-level API that enables you to use BookKeeper without directly interacting with ledgers.</li>
+</ul>
+
+<p>In general, you should choose the API based on how much granular control you need over ledger semantics. The two APIs can also both be used within a single application.</p>
+
+<h2 id="bookies">Bookies</h2>
+
+<blockquote>
+  <p><strong>Bookies</strong> are individual BookKeeper servers that handle ledgers (more specifically, fragments of ledgers). Bookies function as part of an ensemble.</p>
+</blockquote>
+
+<p>A bookie is an individual BookKeeper storage server. Individual bookies store fragments of ledgers, not entire ledgers (for the sake of performance). For any given ledger <strong>L</strong>, an <em>ensemble</em> is the group of bookies storing the entries in <strong>L</strong>.</p>
+
+<p>Whenever entries are written to a ledger, those entries are <span class="pop" id="striped-popover">striped</span> across the ensemble (written to a sub-group of bookies rather than to all bookies).</p>
+
+<h3 id="motivation">Motivation</h3>
+
+<blockquote>
+  <p>BookKeeper was initially inspired by the NameNode server in HDFS but its uses now extend far beyond this.</p>
+</blockquote>
+
+<p>The initial motivation for BookKeeper comes from the <a href="http://hadoop.apache.org/">Hadoop</a> ecosystem. In the <a href="https://wiki.apache.org/hadoop/HDFS">Hadoop Distributed File System</a> (HDFS), a special node called the <a href="https://wiki.apache.org/hadoop/NameNode">NameNode</a> logs all operations in a reliable fashion, which ensures that recovery is possible in case of crashes.</p>
+
+<p>The NameNode, however, served only as initial inspiration for BookKeeper. The applications for BookKeeper extend far beyond this and include essentially any application that requires an append-based storage system. BookKeeper provides a number of advantages for such applications:</p>
+
+<ul>
+  <li>Highly efficient writes</li>
+  <li>High fault tolerance via replication of messages within ensembles of bookies</li>
+  <li>High throughput for write operations via <span class="pop" id="striping-popover">striping</span> (across as many bookies as you wish)</li>
+</ul>
+
+<h2 id="metadata-storage">Metadata storage</h2>
+
+<p>The BookKeeper metadata store maintains all the metadata of the BookKeeper cluster, such as <a href="#ledgers">ledger</a> metadata, available bookies, and so on. Currently, BookKeeper uses <a href="https://zookeeper.apache.org">ZooKeeper</a> for metadata storage.</p>
+
+<h2 id="data-management-in-bookies">Data management in bookies</h2>
+
+<p>Bookies manage data in a <a href="https://en.wikipedia.org/wiki/Log-structured_file_system">log-structured</a> way, which is implemented using three types of files:</p>
+
+<ul>
+  <li><a href="#journals">journals</a></li>
+  <li><a href="#entry-logs">entry logs</a></li>
+  <li><a href="#index-files">index files</a></li>
+</ul>
+
+<h3 id="journals">Journals</h3>
+
+<p>A journal file contains BookKeeper transaction logs. Before any update to a ledger takes place, the bookie ensures that a transaction describing the update is written to non-volatile storage. A new journal file is created once the bookie starts or the older journal file reaches the journal file size threshold.</p>
+
+<h3 id="entry-logs">Entry logs</h3>
+
+<p>An entry log file manages the written entries received from BookKeeper clients. Entries from different ledgers are aggregated and written sequentially, while their offsets are kept as pointers in a <a href="#ledger-cache">ledger cache</a> for fast lookup.</p>
+
+<p>A new entry log file is created once the bookie starts or the older entry log file reaches the entry log size threshold. Old entry log files are removed by the Garbage Collector Thread once they are not associated with any active ledger.</p>
+
+<h3 id="index-files">Index files</h3>
+
+<p>An index file is created for each ledger, which comprises a header and several fixed-length index pages that record the offsets of data stored in entry log files.</p>
+
+<p>Since updating index files would introduce random disk I/O index files are updated lazily by a sync thread running in the background. This ensures speedy performance for updates. Before index pages are persisted to disk, they are gathered in a ledger cache for lookup.</p>

+<p>Ledger indexes pages are cached in a memory pool, which allows for more efficient management of disk head scheduling.</p>
+
+<h3 id="adding-entries">Adding entries</h3>
+
+<p>When a client instructs a <span class="pop" id="bookie-popover">bookie</span> to write an entry to a ledger, the entry will go through the following steps to be persisted on disk:</p>
+
+<ol>
+  <li>The entry is appended to an <a href="#entry-logs">entry log</a></li>
+  <li>The index of the entry is updated in the <a href="#ledger-cache">ledger cache</a></li>
+  <li>A transaction corresponding to this entry update is appended to the <a href="#journals">journal</a></li>
+  <li>A response is sent to the BookKeeper client</li>
+</ol>
+
+<blockquote>
+  <p>For performance reasons, the entry log buffers entries in memory and commits them in batches, while the ledger cache holds index pages in memory and flushes them lazily. This process is described in more detail in the <a href="#data-flush">Data flush</a> section below.</p>
+</blockquote>
+
+<h3 id="data-flush">Data flush</h3>
+
+<p>Ledger index pages are flushed to index files in the following two cases:</p>
+
+<ul>
+  <li>The ledger cache memory limit is reached. There is no more space available to hold newer index pages. Dirty index pages will be evicted from the ledger cache and persisted to index files.</li>
+  <li>A background thread synchronous thread is responsible for flushing index pages from the ledger cache to index files periodically.</li>
+</ul>
+
+<p>Besides flushing index pages, the sync thread is responsible for rolling journal files in case that journal files use too much disk space. The data flush flow in the sync thread is as follows:</p>
+
+<ul>
+  <li>A <code class="highlighter-rouge">LastLogMark</code> is recorded in memory. The <code class="highlighter-rouge">LastLogMark</code> indicates that those entries before it have been persisted (to both index and entry log files) and contains two parts:
+    <ol>
+      <li>A <code class="highlighter-rouge">txnLogId</code> (the file ID of a journal)</li>
+      <li>A <code class="highlighter-rouge">txnLogPos</code> (offset in a journal)</li>
+    </ol>
+  </li>
+  <li>
+    <p>Dirty index pages are flushed from the ledger cache to the index file, and entry log files are flushed to ensure that all buffered entries in entry log files are persisted to disk.</p>
+
+    <p>Ideally, a bookie only needs to flush index pages and entry log files that contain entries before <code class="highlighter-rouge">LastLogMark</code>. There is, however, no such information in the ledger and entry log mapping to journal files. Consequently, the thread flushes the ledger cache and entry log entirely here, and may flush entries after the <code class="highlighter-rouge">LastLogMark</code>. Flushing more is not a problem, though, just redundant.</p>
+  </li>
+  <li>The <code class="highlighter-rouge">LastLogMark</code> is persisted to disk, which means that entries added before <code class="highlighter-rouge">LastLogMark</code> whose entry data and index page were also persisted to disk. It is now time to safely remove journal files created earlier than <code class="highlighter-rouge">txnLogId</code>.</li>
+</ul>
+
+<p>If the bookie has crashed before persisting <code class="highlighter-rouge">LastLogMark</code> to disk, it still has journal files containing entries for which index pages may not have been persisted. Consequently, when this bookie restarts, it inspects journal files to restore those entries and data isn’t lost.</p>
+
+<p>Using the above data flush mechanism, it is safe for the sync thread to skip data flushing when the bookie shuts down. However, in the entry logger it uses a buffered channel to write entries in batches and there might be data buffered in the buffered channel upon a shut down. The bookie needs to ensure that the entry log flushes its buffered data during shutdown. Otherwise, entry log files become corrupted with partial entries.</p>
+
+<h3 id="data-compaction">Data compaction</h3>
+
+<p>On bookies, entries of different ledgers are interleaved in entry log files. A bookie runs a garbage collector thread to delete un-associated entry log files to reclaim disk space. If a given entry log file contains entries from a ledger that has not been deleted, then the entry log file would never be removed and the occupied disk space never reclaimed. In order to avoid such a case, a bookie server compacts entry log files in a garbage collector thread to reclaim disk space.</p>
+
+<p>There are two kinds of compaction running with different frequency: minor compaction and major compaction. The differences between minor compaction and major compaction lies in their threshold value and compaction interval.</p>
+
+<ul>
+  <li>The garbage collection threshold is the size percentage of an entry log file occupied by those undeleted ledgers. The default minor compaction threshold is 0.2, while the major compaction threshold is 0.8.</li>
+  <li>The garbage collection interval is how frequently to run the compaction. The default minor compaction interval is 1 hour, while the major compaction threshold is 1 day.</li>
+</ul>
+
+<blockquote>
+  <p>If either the threshold or interval is set to less than or equal to zero, compaction is disabled.</p>
+</blockquote>
+
+<p>The data compaction flow in the garbage collector thread is as follows:</p>
+
+<ul>
+  <li>The thread scans entry log files to get their entry log metadata, which records a list of ledgers comprising an entry log and their corresponding percentages.</li>
+  <li>With the normal garbage collection flow, once the bookie determines that a ledger has been deleted, the ledger will be removed from the entry log metadata and the size of the entry log reduced.</li>
+  <li>If the remaining size of an entry log file reaches a specified threshold, the entries of active ledgers in the entry log will be copied to a new entry log file.</li>
+  <li>Once all valid entries have been copied, the old entry log file is deleted.</li>
+</ul>

+<h2 id="zookeeper-metadata">ZooKeeper metadata</h2>
+
+<p>BookKeeper requires a ZooKeeper installation for storing <a href="#ledger">ledger</a> metadata. Whenever you construct a <a href="../../api/javadoc/org/apache/bookkeeper/client/BookKeeper"><code class="highlighter-rouge">BookKeeper</code></a> client object, you need to pass a list of ZooKeeper servers as a parameter to the constructor, like this:</p>

+
+<h2 id="ledger-manager">Ledger manager</h2>
+
+<p>A <em>ledger manager</em> handles ledgers’ metadata (which is stored in ZooKeeper). BookKeeper offers two types of ledger managers: the <a href="#flat-ledger-manager">flat ledger manager</a> and the <a href="#hierarchical-ledger-manager">hierarchical ledger manager</a>. Both ledger managers extend the <a href="../../api/javadoc/org/apache/bookkeeper/meta/AbstractZkLedgerManager"><code class="highlighter-rouge">AbstractZkLedgerManager</code></a> abstract class.</p>
+
+<h3 id="hierarchical-ledger-manager">Hierarchical ledger manager</h3>
+
+<blockquote>
+  <p>default ledger manager.</p>
+
+  <p>The hierarchical ledger manager is able to manage very large numbers of BookKeeper ledgers (&gt; 50,000).</p>
+</blockquote>
+
+<p>The <em>hierarchical ledger manager</em>, implemented in the <a href="../../api/javadoc/org/apache/bookkeeper/meta/HierarchicalLedgerManager"><code class="highlighter-rouge">HierarchicalLedgerManager</code></a> class, first obtains a global unique ID from ZooKeeper using an <a href="https://zookeeper.apache.org/doc/current/api/org/apache/zookeeper/CreateMode.html#EPHEMERAL_SEQUENTIAL"><code class="highlighter-rouge">EPHEMERAL_SEQUENTIAL</code></a> znode. Since ZooKeeper’s sequence counter has a format of <code class="highlighter-rouge">%10d</code> (10 digits with 0 padding, for example <code class="highlighter-rouge">&lt;path&gt;0000000001</code>), the hierarchical ledger manager splits the generated ID into 3 parts:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="o">{</span>level1 <span class="o">(</span>2 digits<span class="o">)}{</span>level2 <span class="o">(</span>4 digits<span class="o">)}{</span>level3 <span class="o">(</span>4 digits<span class="o">)}</span>
+</code></pre></div></div>
+
+<p>These three parts are used to form the actual ledger node path to store ledger metadata:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="o">{</span>ledgers_root_path<span class="o">}</span>/<span class="o">{</span>level1<span class="o">}</span>/<span class="o">{</span>level2<span class="o">}</span>/L<span class="o">{</span>level3<span class="o">}</span>
+</code></pre></div></div>
+
+<p>For example, ledger 0000000001 is split into three parts, 00, 0000, and 00001, and stored in znode <code class="highlighter-rouge">/{ledgers_root_path}/00/0000/L0001</code>. Each znode could have as many 10,000 ledgers, which avoids the problem of the child list being larger than the maximum ZooKeeper packet size (which is the <a href="https://issues.apache.org/jira/browse/BOOKKEEPER-39">limitation</a> that initially prompted the creation of the hierarchical ledger manager).</p>
+
+<h3 id="flat-ledger-manager">Flat ledger manager</h3>
+
+<blockquote>
+  <p>deprecated since 4.7.0, not recommand now.</p>
+</blockquote>
+
+<p>The <em>flat ledger manager</em>, implemented in the <a href="../../api/javadoc/org/apache/bookkeeper/meta/FlatLedgerManager.html"><code class="highlighter-rouge">FlatLedgerManager</code></a> class, stores all ledgers’ metadata in child nodes of a single ZooKeeper path. The flat ledger manager creates <a href="https://zookeeper.apache.org/doc/trunk/zookeeperProgrammers.html#Sequence+Nodes+--+Unique+Naming">sequential nodes</a> to ensure the uniqueness of the ledger ID and prefixes all nodes with <code class="highlighter-rouge">L</code>. Bookie servers manage their own active ledgers in a hash map so that it’s easy to find which ledgers have been deleted from ZooKeeper and then garbage collect them.</p>
+
+<p>The flat ledger manager’s garbage collection follow proceeds as follows:</p>
+
+<ul>
+  <li>All existing ledgers are fetched from ZooKeeper (<code class="highlighter-rouge">zkActiveLedgers</code>)</li>
+  <li>All ledgers currently active within the bookie are fetched (<code class="highlighter-rouge">bkActiveLedgers</code>)</li>
+  <li>The currently actively ledgers are looped through to determine which ledgers don’t currently exist in ZooKeeper. Those are then garbage collected.</li>
+  <li>The <em>hierarchical ledger manager</em> stores ledgers’ metadata in two-level <a href="https://zookeeper.apache.org/doc/current/zookeeperOver.html#Nodes+and+ephemeral+nodes">znodes</a>.</li>

+
+<h2 id="download">Download</h2>
+
+<p>You can download Apache BookKeeper releases from one of many <a href="http://www.apache.org/dyn/closer.cgi/bookkeeper">Apache mirrors</a>. Here’s an example for the <a href="http://apache.claz.org/bookkeeper">apache.claz.org</a> mirror:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>curl <span class="nt">-O</span> http://apache.claz.org/bookkeeper/bookkeeper-4.13.0/bookkeeper-4.13.0-src.tar.gz

+</code></pre></div></div>
+
+<h2 id="clone">Clone</h2>
+
+<p>To build BookKeeper from source, clone the repository, either from the <a href="https://github.com/apache/bookkeeper">GitHub mirror</a> or from the <a href="http://git.apache.org/bookkeeper.git/">Apache repository</a>:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># From the GitHub mirror</span>
+<span class="nv">$ </span>git clone https://github.com/apache/bookkeeper

+<span class="nv">$ </span>git clone git://git.apache.org/bookkeeper.git/
+</code></pre></div></div>
+
+<h2 id="build-using-maven">Build using Maven</h2>
+
+<p>Once you have the BookKeeper on your local machine, either by <a href="#download">downloading</a> or <a href="#clone">cloning</a> it, you can then build BookKeeper from source using Maven:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>mvn package
+</code></pre></div></div>
+

+          <p>In the 4.5.0 release, the BookKeeper community added a number of features that can be used, together or separately, to secure a BookKeeper cluster.
+The following security measures are currently supported:</p>
+
+<ol>
+  <li>Authentication of connections to bookies from clients, using either <a href="../tls">TLS</a> or <a href="../sasl">SASL (Kerberos)</a>.</li>
+  <li>Authentication of connections from clients, bookies, autorecovery daemons to <a href="../zookeeper">ZooKeeper</a>, when using zookeeper based ledger managers.</li>
+  <li>Encryption of data transferred between bookies and clients, between bookies and autorecovery daemons using <a href="../tls">TLS</a>.</li>
+</ol>
+
+<p>It’s worth noting that security is optional - non-secured clusters are supported, as well as a mix of authenticated, unauthenticated, encrypted and non-encrypted clients.</p>
+
+<p>NOTE: authorization is not yet available in 4.5.0. The Apache BookKeeper community is looking to add this feature in subsequent releases.</p>

+  <li>The <code class="highlighter-rouge">Client</code> section is used to authenticate a SASL connection with ZooKeeper. It also allows the bookies to set ACLs on ZooKeeper nodes
+ which locks these nodes down so that only the bookies can modify it. It is necessary to have the same primary name across all bookies.
+ If you want to use a section name other than <code class="highlighter-rouge">Client</code>, set the system property <code class="highlighter-rouge">zookeeper.sasl.client</code> to the appropriate name
+ (e.g <code class="highlighter-rouge">-Dzookeeper.sasl.client=ZKClient</code>).</li>
+  <li>ZooKeeper uses <code class="highlighter-rouge">zookeeper</code> as the service name by default. If you want to change this, set the system property

+
+<p>If your organization is already using a Kerberos server (for example, by using <code class="highlighter-rouge">Active Directory</code>), there is no need to
+install a new server just for BookKeeper. Otherwise you will need to install one, your Linux vendor likely has packages
+for <code class="highlighter-rouge">Kerberos</code> and a short guide on how to install and configure it (<a href="https://help.ubuntu.com/community/Kerberos">Ubuntu</a>,
+<a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Managing_Smart_Cards/installing-kerberos.html">Redhat</a>).
+Note that if you are using Oracle Java, you will need to download JCE policy files for your Java version and copy them to <code class="highlighter-rouge">$JAVA_HOME/jre/lib/security</code>.</p>
+
+<h4 id="kerberos-principals">Kerberos Principals</h4>
+
+<p>If you are using the organization’s Kerberos or Active Directory server, ask your Kerberos administrator for a principal
+for each Bookie in your cluster and for every operating system user that will access BookKeeper with Kerberos authentication
+(via clients and tools).</p>
+
+<p>If you have installed your own Kerberos, you will need to create these principals yourself using the following commands:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nb">sudo</span> /usr/sbin/kadmin.local <span class="nt">-q</span> <span class="s1">'addprinc -randkey bookkeeper/{hostname}@{REALM}'</span>

+  <li>
+    <p>Add a suitably modified JAAS file similar to the one below to each Bookie’s config directory, let’s call it <code class="highlighter-rouge">bookie_jaas.conf</code>

+
+    <div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code> Bookie {

+          <p>Apache BookKeeper allows clients and autorecovery daemons to communicate over TLS, although this is not enabled by default.</p>
+
+<h2 id="overview">Overview</h2>
+
+<p>The bookies need their own key and certificate in order to use TLS. Clients can optionally provide a key and a certificate
+for mutual authentication.  Each bookie or client can also be configured with a truststore, which is used to
+determine which certificates (bookie or client identities) to trust (authenticate).</p>
+
+<p>The truststore can be configured in many ways. To understand the truststore, consider the following two examples:</p>
+
+<ol>
+  <li>the truststore contains one or many certificates;</li>
+  <li>it contains a certificate authority (CA).</li>
+</ol>
+
+<p>In (1), with a list of certificates, the bookie or client will trust any certificate listed in the truststore.
+In (2), with a CA, the bookie or client will trust any certificate that was signed by the CA in the truststore.</p>
+
+<p>(TBD: benefits)</p>
+
+<h2 id="-generate-tls-key-and-certificate"><a name="bookie-keystore"></a> Generate TLS key and certificate</h2>
+
+<p>The first step of deploying TLS is to generate the key and the certificate for each machine in the cluster.
+You can use Java’s <code class="highlighter-rouge">keytool</code> utility to accomplish this task. We will generate the key into a temporary keystore
+initially so that we can export and sign it later with CA.</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>keytool <span class="nt">-keystore</span> bookie.keystore.jks <span class="nt">-alias</span> localhost <span class="nt">-validity</span> <span class="o">{</span>validity<span class="o">}</span> <span class="nt">-genkey</span>
+</code></pre></div></div>
+
+<p>You need to specify two parameters in the above command:</p>
+
+<ol>
+  <li><code class="highlighter-rouge">keystore</code>: the keystore file that stores the certificate. The <em>keystore</em> file contains the private key of
+ the certificate; hence, it needs to be kept safely.</li>
+  <li><code class="highlighter-rouge">validity</code>: the valid time of the certificate in days.</li>
+</ol>
+
+<div class="alert alert-success">
+Ensure that common name (CN) matches exactly with the fully qualified domain name (FQDN) of the server.
+The client compares the CN with the DNS domain name to ensure that it is indeed connecting to the desired server, not a malicious one.
+</div>
+
+<h2 id="creating-your-own-ca">Creating your own CA</h2>
+
+<p>After the first step, each machine in the cluster has a public-private key pair, and a certificate to identify the machine.
+The certificate, however, is unsigned, which means that an attacker can create such a certificate to pretend to be any machine.</p>
+
+<p>Therefore, it is important to prevent forged certificates by signing them for each machine in the cluster.
+A <code class="highlighter-rouge">certificate authority (CA)</code> is responsible for signing certificates. CA works likes a government that issues passports —
+the government stamps (signs) each passport so that the passport becomes difficult to forge. Other governments verify the stamps
+to ensure the passport is authentic. Similarly, the CA signs the certificates, and the cryptography guarantees that a signed
+certificate is computationally difficult to forge. Thus, as long as the CA is a genuine and trusted authority, the clients have
+high assurance that they are connecting to the authentic machines.</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl req <span class="nt">-new</span> <span class="nt">-x509</span> <span class="nt">-keyout</span> ca-key <span class="nt">-out</span> ca-cert <span class="nt">-days</span> 365
+</code></pre></div></div>
+
+<p>The generated CA is simply a <em>public-private</em> key pair and certificate, and it is intended to sign other certificates.</p>
+
+<p>The next step is to add the generated CA to the clients’ truststore so that the clients can trust this CA:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>keytool <span class="nt">-keystore</span> bookie.truststore.jks <span class="nt">-alias</span> CARoot <span class="nt">-import</span> <span class="nt">-file</span> ca-cert
+</code></pre></div></div>
+
+<p>NOTE: If you configure the bookies to require client authentication by setting <code class="highlighter-rouge">sslClientAuthentication</code> to <code class="highlighter-rouge">true</code> on the
+<a href="../../reference/config">bookie config</a>, then you must also provide a truststore for the bookies and it should have all the CA
+certificates that clients keys were signed by.</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>keytool <span class="nt">-keystore</span> client.truststore.jks <span class="nt">-alias</span> CARoot <span class="nt">-import</span> <span class="nt">-file</span> ca-cert
+</code></pre></div></div>
+
+<p>In contrast to the keystore, which stores each machine’s own identity, the truststore of a client stores all the certificates
+that the client should trust. Importing a certificate into one’s truststore also means trusting all certificates that are signed
+by that certificate. As the analogy above, trusting the government (CA) also means trusting all passports (certificates) that
+it has issued. This attribute is called the chain of trust, and it is particularly useful when deploying TLS on a large BookKeeper cluster.
+You can sign all certificates in the cluster with a single CA, and have all machines share the same truststore that trusts the CA.
+That way all machines can authenticate all other machines.</p>
+
+<h2 id="signing-the-certificate">Signing the certificate</h2>
+
+<p>The next step is to sign all certificates in the keystore with the CA we generated. First, you need to export the certificate from the keystore:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>keytool <span class="nt">-keystore</span> bookie.keystore.jks <span class="nt">-alias</span> localhost <span class="nt">-certreq</span> <span class="nt">-file</span> cert-file
+</code></pre></div></div>
+
+<p>Then sign it with the CA:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl x509 <span class="nt">-req</span> <span class="nt">-CA</span> ca-cert <span class="nt">-CAkey</span> ca-key <span class="nt">-in</span> cert-file <span class="nt">-out</span> cert-signed <span class="nt">-days</span> <span class="o">{</span>validity<span class="o">}</span> <span class="nt">-CAcreateserial</span> <span class="nt">-passin</span> pass:<span class="o">{</span>ca-password<span class="o">}</span>
+</code></pre></div></div>
+
+<p>Finally, you need to import both the certificate of the CA and the signed certificate into the keystore:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>keytool <span class="nt">-keystore</span> bookie.keystore.jks <span class="nt">-alias</span> CARoot <span class="nt">-import</span> <span class="nt">-file</span> ca-cert
+keytool <span class="nt">-keystore</span> bookie.keystore.jks <span class="nt">-alias</span> localhost <span class="nt">-import</span> <span class="nt">-file</span> cert-signed
+</code></pre></div></div>
+
+<p>The definitions of the parameters are the following:</p>
+
+<ol>
+  <li><code class="highlighter-rouge">keystore</code>: the location of the keystore</li>
+  <li><code class="highlighter-rouge">ca-cert</code>: the certificate of the CA</li>
+  <li><code class="highlighter-rouge">ca-key</code>: the private key of the CA</li>
+  <li><code class="highlighter-rouge">ca-password</code>: the passphrase of the CA</li>
+  <li><code class="highlighter-rouge">cert-file</code>: the exported, unsigned certificate of the bookie</li>
+  <li><code class="highlighter-rouge">cert-signed</code>: the signed certificate of the bookie</li>
+</ol>
+
+<p>(TBD: add a script to automatically generate truststores and keystores.)</p>
+
+<h2 id="configuring-bookies">Configuring Bookies</h2>
+
+<p>Bookies support TLS for connections on the same service port. In order to enable TLS, you need to configure <code class="highlighter-rouge">tlsProvider</code> to be either
+<code class="highlighter-rouge">JDK</code> or <code class="highlighter-rouge">OpenSSL</code>. If <code class="highlighter-rouge">OpenSSL</code> is configured, it will use <code class="highlighter-rouge">netty-tcnative-boringssl-static</code>, which loads a corresponding binding according
+to the platforms to run bookies.</p>
+
+<blockquote>
+  <p>Current <code class="highlighter-rouge">OpenSSL</code> implementation doesn’t depend on the system installed OpenSSL library. If you want to leverage the OpenSSL installed on
+the system, you can check <a href="http://netty.io/wiki/forked-tomcat-native.html">this example</a> on how to replaces the JARs on the classpath with
+netty bindings to leverage installed OpenSSL.</p>
+</blockquote>
+
+<p>The following TLS configs are needed on the bookie side:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">tlsProvider</span><span class="o">=</span>OpenSSL
+<span class="c"># key store</span>
+<span class="nv">tlsKeyStoreType</span><span class="o">=</span>JKS
+<span class="nv">tlsKeyStore</span><span class="o">=</span>/var/private/tls/bookie.keystore.jks
+<span class="nv">tlsKeyStorePasswordPath</span><span class="o">=</span>/var/private/tls/bookie.keystore.passwd
+<span class="c"># trust store</span>
+<span class="nv">tlsTrustStoreType</span><span class="o">=</span>JKS
+<span class="nv">tlsTrustStore</span><span class="o">=</span>/var/private/tls/bookie.truststore.jks
+<span class="nv">tlsTrustStorePasswordPath</span><span class="o">=</span>/var/private/tls/bookie.truststore.passwd
+</code></pre></div></div>
+
+<p>NOTE: it is important to restrict access to the store files and corresponding password files via filesystem permissions.</p>
+
+<p>Optional settings that are worth considering:</p>
+
+<ol>
+  <li>tlsClientAuthentication=false: Enable/Disable using TLS for authentication. This config when enabled will authenticate the other end
+ of the communication channel. It should be enabled on both bookies and clients for mutual TLS.</li>
+  <li>tlsEnabledCipherSuites= A cipher suite is a named combination of authentication, encryption, MAC and key exchange
+ algorithm used to negotiate the security settings for a network connection using TLS network protocol. By default,
+ it is null. <a href="https://www.openssl.org/docs/man1.0.2/apps/ciphers.html">OpenSSL Ciphers</a>
+ <a href="http://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#ciphersuites">JDK Ciphers</a></li>
+  <li>tlsEnabledProtocols = TLSv1.2,TLSv1.1,TLSv1 (list out the TLS protocols that you are going to accept from clients).
+ By default, it is not set.</li>
+</ol>
+
+<p>To verify the bookie’s keystore and truststore are setup correctly you can run the following command:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl s_client <span class="nt">-debug</span> <span class="nt">-connect</span> localhost:3181 <span class="nt">-tls1</span>
+</code></pre></div></div>
+
+<p>NOTE: TLSv1 should be listed under <code class="highlighter-rouge">tlsEnabledProtocols</code>.</p>
+
+<p>In the output of this command you should see the server’s certificate:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt">-----BEGIN</span> CERTIFICATE-----
+<span class="o">{</span>variable sized random bytes<span class="o">}</span>
+<span class="nt">-----END</span> CERTIFICATE-----
+</code></pre></div></div>
+
+<p>If the certificate does not show up or if there are any other error messages then your keystore is not setup correctly.</p>
+
+<h2 id="configuring-clients">Configuring Clients</h2>
+
+<p>TLS is supported only for the new BookKeeper client (BookKeeper versions 4.5.0 and higher), the older clients are not
+supported. The configs for TLS will be the same as bookies.</p>
+
+<p>If client authentication is not required by the bookies, the following is a minimal configuration example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">tlsProvider</span><span class="o">=</span>OpenSSL
+<span class="nv">clientTrustStore</span><span class="o">=</span>/var/private/tls/client.truststore.jks
+<span class="nv">clientTrustStorePasswordPath</span><span class="o">=</span>/var/private/tls/client.truststore.passwd
+</code></pre></div></div>
+
+<p>If client authentication is required, then a keystore must be created for each client, and the bookies’ truststores must
+trust the certificate in the client’s keystore. This may be done using commands that are similar to what we used for
+the <a href="#bookie-keystore">bookie keystore</a>.</p>
+
+<p>And the following must also be configured:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">tlsClientAuthentication</span><span class="o">=</span><span class="nb">true
+</span><span class="nv">clientKeyStore</span><span class="o">=</span>/var/private/tls/client.keystore.jks
+<span class="nv">clientKeyStorePasswordPath</span><span class="o">=</span>/var/private/tls/client.keystore.passwd
+</code></pre></div></div>
+
+<p>NOTE: it is important to restrict access to the store files and corresponding password files via filesystem permissions.</p>
+
+<p>(TBD: add example to use tls in bin/bookkeeper script?)</p>
+
+<h2 id="enabling-tls-logging">Enabling TLS Logging</h2>
+
+<p>You can enable TLS debug logging at the JVM level by starting the bookies and/or clients with <code class="highlighter-rouge">javax.net.debug</code> system property. For example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt">-Djavax</span>.net.debug<span class="o">=</span>all
+</code></pre></div></div>
+
+<p>You can find more details on this in <a href="http://docs.oracle.com/javase/8/docs/technotes/guides/security/jsse/ReadDebug.html">Oracle documentation</a> on
+<a href="http://docs.oracle.com/javase/8/docs/technotes/guides/security/jsse/ReadDebug.html">debugging SSL/TLS connections</a>.</p>

+
+<p>To enable <code class="highlighter-rouge">ZooKeeper</code> authentication on Bookies or Clients, there are two necessary steps:</p>
+
+<ol>
+  <li>Create a <code class="highlighter-rouge">JAAS</code> login file and set the appropriate system property to point to it as described in <a href="../sasl#notes">GSSAPI (Kerberos)</a>.</li>
+  <li>Set the configuration property <code class="highlighter-rouge">zkEnableSecurity</code> in each bookie to <code class="highlighter-rouge">true</code>.</li>
+</ol>
+
+<p>The metadata stored in <code class="highlighter-rouge">ZooKeeper</code> is such that only certain clients will be able to modify and read the corresponding znodes.
+The rationale behind this decision is that the data stored in ZooKeeper is not sensitive, but inappropriate manipulation of znodes can cause cluster
+disruption.</p>
+
+<h2 id="migrating-clusters">Migrating Clusters</h2>
+
+<p>If you are running a version of BookKeeper that does not support security or simply with security disabled, and you want to make the cluster secure,
+then you need to execute the following steps to enable ZooKeeper authentication with minimal disruption to your operations.</p>
+
+<ol>
+  <li>Perform a rolling restart setting the <code class="highlighter-rouge">JAAS</code> login file, which enables bookie or clients to authenticate. At the end of the rolling restart,
+ bookies (or clients) are able to manipulate znodes with strict ACLs, but they will not create znodes with those ACLs.</li>
+  <li>Perform a second rolling restart of bookies, this time setting the configuration parameter <code class="highlighter-rouge">zkEnableSecurity</code> to true, which enables the use
+ of secure ACLs when creating znodes.</li>
+  <li>Currently we don’t have provide a tool to set acls on old znodes. You are recommended to set it manually using ZooKeeper tools.</li>
+</ol>
+
+<p>It is also possible to turn off authentication in a secured cluster. To do it, follow these steps:</p>
+
+<ol>
+  <li>Perform a rolling restart of bookies setting the <code class="highlighter-rouge">JAAS</code> login file, which enable bookies to authenticate, but setting <code class="highlighter-rouge">zkEnableSecurity</code> to <code class="highlighter-rouge">false</code>.
+ At the end of rolling restart, bookies stop creating znodes with secure ACLs, but are still able to authenticate and manipulate all znodes.</li>
+  <li>You can use ZooKeeper tools to manually reset all ACLs under the znode set in <code class="highlighter-rouge">zkLedgersRootPath</code>, which defaults to <code class="highlighter-rouge">/ledgers</code>.</li>
+  <li>Perform a second rolling restart of bookies, this time omitting the system property that sets the <code class="highlighter-rouge">JAAS</code> login file.</li>
+</ol>
+
+<h2 id="migrating-the-zookeeper-ensemble">Migrating the ZooKeeper ensemble</h2>
+
+<p>It is also necessary to enable authentication on the <code class="highlighter-rouge">ZooKeeper</code> ensemble. To do it, we need to perform a rolling restart of the ensemble and
+set a few properties. Please refer to the ZooKeeper documentation for more details.</p>
