+  <div class="entry-content">
+    <p>This blog post describes how the 1.0 release of Apache Kudu (incubating) will
+support fault tolerance for the Kudu master, finally eliminating Kudu’s last
+single point of failure.</p>
+
+<!--more-->
+
+<p>As those of you who follow this blog know by now, replication is a signature
+feature in Kudu. Replication is used to provide fault tolerance for all loaded
+data. By implementing the Raft consensus protocol, Kudu guarantees that a tablet
+replicated <strong>2N+1</strong> times can tolerate up to <strong>N</strong> failures.</p>
+
+<p>What you may not know is that Kudu replicates its metadata, too. That is, the
+Kudu master stores all table and tablet metadata in a single “master” tablet.
+As a regular Kudu tablet itself, this master tablet may be replicated with
+Raft. As such, the Kudu master is a special kind of tablet server whose primary
+job is to host a single replica of the master tablet.</p>
+
+<p>When we launched Kudu’s first beta, support for replicated masters had been
+implemented but was too fragile to be anything but experimental. One of our
+goals for Kudu’s 1.0 release is to improve replicated master support so that it
+can be safely enabled in production clusters.</p>
+
+<h1 id="how-master-replication-works">How master replication works</h1>
+
+<p>To use replicated masters, a Kudu operator must deploy some number of Kudu
+masters, providing the hostname and port number of each master in the group via
+the <code>--master_address</code> command line option. For example, each master in a
+three-node deployment should be started with
+<code>--master_address=&lt;host1:port1&gt;,&lt;host2:port2&gt;&lt;host3:port3&gt;</code>. In Raft parlance,
+this group of masters is known as a <em>Raft configuration</em>.</p>
+
+<p>At startup, a Raft configuration of masters will hold a leader election and
+elect one master as the leader. The leader master is responsible for servicing
+both tablet server heartbeats as well as client requests. The remaining masters
+are followers: they participate in Raft consensus and replicate writes sent by
+the leader, but are otherwise idle. Any client requests they receive are
+rejected. Likewise, all tablet server heartbeats they receive are ignored. If
+the leader master ever dies or steps down, the remaining replicas hold an
+election to determine the new leader.</p>
+
+<p>All persistent master metadata is stored in the single replicated “master”
+tablet. Every row in this tablet represents either a table or a tablet. Table
+records include unique table identifiers, the table’s schema, and other bits of
+information. Tablet records include a unique identifier, the tablet’s Raft
+configuration, and other information.</p>
+
+<p>What master metadata is replicated?</p>
+
+<ol>
+  <li>Table and tablet existence, via <strong>CreateTable()</strong> and <strong>DeleteTable()</strong>.
+Every new tablet record also includes an initial Raft configuration.</li>
+  <li>Schema changes, via <strong>AlterTable()</strong> and tablet server heartbeats.</li>
+  <li>Tablet server Raft configuration changes, via tablet server heartbeats.
+These include both the list of Raft peers (may have changed due to
+under-replication) as well as the current leader (may have changed due to
+an election).</li>
+</ol>
+
+<p>Scanning the master tablet to service every heartbeat or client request would be
+slow, so the leader master caches all master metadata in memory. The caches are
+only updated after a metadata change is successfully replicated; in this way
+they are always consistent with the on-disk tablet. When a new leader master is
+elected, it scans the entire master tablet and uses the metadata to rebuild its
+in-memory caches.</p>
+
+<h1 id="communication-with-replicated-masters">Communication with replicated masters</h1>
+
+<p>All tablet servers start up with location information for the entire master Raft
+configuration and will periodically heartbeat to every master. Similarly,
+clients are also configured with the locations of all masters. Unlike tablet
+servers, they always communicate with the leader master as follower masters will
+reject client requests. To do this, clients must determine which master is the
+leader before sending the first request as well as whenever any request fails
+with a <code>NOT_THE_LEADER</code> error.</p>
+
+<h1 id="remaining-work-for-kudu-10">Remaining work for Kudu 1.0</h1>
+
+<p><a href="https://issues.apache.org/jira/browse/KUDU-422">KUDU-422</a> tracks the remaining
+master replication work. The guts of this feature have been implemented as far
+back as early 2015; the remaining work has been focused on fixing bugs that
+manifest only under specific conditions. For example, we’ve observed failures in
+DDL operations (e.g. <strong>CreateTable()</strong>) that only materialize upon the
+completion of a master leader election. These failures highlight some of the
+gaps in our testing regimen: we need a robust stress test that repeatedly
+performs such operations while holding master leader elections.</p>
+
+<p>That said, there is one remaining work item of larger scope: there’s no
+mechanism with which to perform a Raft configuration change for replicated
+masters. Such a mechanism would have multiple uses:</p>
+
+<ol>
+  <li>Migrating from a single-node master deployment to a fully replicated
+three-node (or five-node) deployment.</li>
+  <li>Replacing a failed master with a new one.</li>
+</ol>
+
+<p>This is being tracked by
+<a href="https://issues.apache.org/jira/browse/KUDU-1474">KUDU-1474</a>, and there’s been
+<a href="http://gerrit.cloudera.org:8080/3393">some discussion</a> around a design, but
+nothing has been implemented yet. Stay tuned!</p>

+support fault tolerance for the Kudu master, finally eliminating Kudu’s last
+single point of failure.&lt;/p&gt;
+
+&lt;!--more--&gt;
+
+&lt;p&gt;As those of you who follow this blog know by now, replication is a signature
+feature in Kudu. Replication is used to provide fault tolerance for all loaded
+data. By implementing the Raft consensus protocol, Kudu guarantees that a tablet
+replicated &lt;strong&gt;2N+1&lt;/strong&gt; times can tolerate up to &lt;strong&gt;N&lt;/strong&gt; failures.&lt;/p&gt;
+
+&lt;p&gt;What you may not know is that Kudu replicates its metadata, too. That is, the
+Kudu master stores all table and tablet metadata in a single “master” tablet.
+As a regular Kudu tablet itself, this master tablet may be replicated with
+Raft. As such, the Kudu master is a special kind of tablet server whose primary
+job is to host a single replica of the master tablet.&lt;/p&gt;
+
+&lt;p&gt;When we launched Kudu’s first beta, support for replicated masters had been
+implemented but was too fragile to be anything but experimental. One of our
+goals for Kudu’s 1.0 release is to improve replicated master support so that it
+can be safely enabled in production clusters.&lt;/p&gt;
+
+&lt;h1 id=&quot;how-master-replication-works&quot;&gt;How master replication works&lt;/h1&gt;
+
+&lt;p&gt;To use replicated masters, a Kudu operator must deploy some number of Kudu
+masters, providing the hostname and port number of each master in the group via
+the &lt;code&gt;--master_address&lt;/code&gt; command line option. For example, each master in a
+three-node deployment should be started with
+&lt;code&gt;--master_address=&amp;lt;host1:port1&amp;gt;,&amp;lt;host2:port2&amp;gt;&amp;lt;host3:port3&amp;gt;&lt;/code&gt;. In Raft parlance,
+this group of masters is known as a &lt;em&gt;Raft configuration&lt;/em&gt;.&lt;/p&gt;
+
+&lt;p&gt;At startup, a Raft configuration of masters will hold a leader election and
+elect one master as the leader. The leader master is responsible for servicing
+both tablet server heartbeats as well as client requests. The remaining masters
+are followers: they participate in Raft consensus and replicate writes sent by
+the leader, but are otherwise idle. Any client requests they receive are
+rejected. Likewise, all tablet server heartbeats they receive are ignored. If
+the leader master ever dies or steps down, the remaining replicas hold an
+election to determine the new leader.&lt;/p&gt;
+
+&lt;p&gt;All persistent master metadata is stored in the single replicated “master”
+tablet. Every row in this tablet represents either a table or a tablet. Table
+records include unique table identifiers, the table’s schema, and other bits of
+information. Tablet records include a unique identifier, the tablet’s Raft
+configuration, and other information.&lt;/p&gt;
+
+&lt;p&gt;What master metadata is replicated?&lt;/p&gt;
+
+&lt;ol&gt;
+  &lt;li&gt;Table and tablet existence, via &lt;strong&gt;CreateTable()&lt;/strong&gt; and &lt;strong&gt;DeleteTable()&lt;/strong&gt;.
+Every new tablet record also includes an initial Raft configuration.&lt;/li&gt;
+  &lt;li&gt;Schema changes, via &lt;strong&gt;AlterTable()&lt;/strong&gt; and tablet server heartbeats.&lt;/li&gt;
+  &lt;li&gt;Tablet server Raft configuration changes, via tablet server heartbeats.
+These include both the list of Raft peers (may have changed due to
+under-replication) as well as the current leader (may have changed due to
+an election).&lt;/li&gt;
+&lt;/ol&gt;
+
+&lt;p&gt;Scanning the master tablet to service every heartbeat or client request would be
+slow, so the leader master caches all master metadata in memory. The caches are
+only updated after a metadata change is successfully replicated; in this way
+they are always consistent with the on-disk tablet. When a new leader master is
+elected, it scans the entire master tablet and uses the metadata to rebuild its
+in-memory caches.&lt;/p&gt;
+
+&lt;h1 id=&quot;communication-with-replicated-masters&quot;&gt;Communication with replicated masters&lt;/h1&gt;
+
+&lt;p&gt;All tablet servers start up with location information for the entire master Raft
+configuration and will periodically heartbeat to every master. Similarly,
+clients are also configured with the locations of all masters. Unlike tablet
+servers, they always communicate with the leader master as follower masters will
+reject client requests. To do this, clients must determine which master is the
+leader before sending the first request as well as whenever any request fails
+with a &lt;code&gt;NOT_THE_LEADER&lt;/code&gt; error.&lt;/p&gt;
+
+&lt;h1 id=&quot;remaining-work-for-kudu-10&quot;&gt;Remaining work for Kudu 1.0&lt;/h1&gt;
+
+&lt;p&gt;&lt;a href=&quot;https://issues.apache.org/jira/browse/KUDU-422&quot;&gt;KUDU-422&lt;/a&gt; tracks the remaining
+master replication work. The guts of this feature have been implemented as far
+back as early 2015; the remaining work has been focused on fixing bugs that
+manifest only under specific conditions. For example, we’ve observed failures in
+DDL operations (e.g. &lt;strong&gt;CreateTable()&lt;/strong&gt;) that only materialize upon the
+completion of a master leader election. These failures highlight some of the
+gaps in our testing regimen: we need a robust stress test that repeatedly
+performs such operations while holding master leader elections.&lt;/p&gt;
+
+&lt;p&gt;That said, there is one remaining work item of larger scope: there’s no
+mechanism with which to perform a Raft configuration change for replicated
+masters. Such a mechanism would have multiple uses:&lt;/p&gt;
+
+&lt;ol&gt;
+  &lt;li&gt;Migrating from a single-node master deployment to a fully replicated
+three-node (or five-node) deployment.&lt;/li&gt;
+  &lt;li&gt;Replacing a failed master with a new one.&lt;/li&gt;
+&lt;/ol&gt;
+
+&lt;p&gt;This is being tracked by
+&lt;a href=&quot;https://issues.apache.org/jira/browse/KUDU-1474&quot;&gt;KUDU-1474&lt;/a&gt;, and there’s been
+&lt;a href=&quot;http://gerrit.cloudera.org:8080/3393&quot;&gt;some discussion&lt;/a&gt; around a design, but
+nothing has been implemented yet. Stay tuned!&lt;/p&gt;</content><author><name>Adar Dembo</name></author><summary>This blog post describes how the 1.0 release of Apache Kudu (incubating) will

-    In the context of making multi-master reliable in 1.0, Adar Dembo posted a design document
-on how to handle permanent master failures. Currently the master&amp;#8217;s code is missing some features
-like remote bootstrap which makes it possible for a new replica to download a snapshot of the data
-from the leader replica.
