| <p>Ozone is designed to work with HDFS. So it is easy to deploy ozone in an |
| existing HDFS cluster.</p> |
| |
| <p>Ozone does <em>not</em> support security today. It is a work in progress and tracked |
| in |
| <a href="https://issues.apache.org/jira/browse/HDDS-4">HDDS-4</a>. If you enable ozone |
| in a secure HDFS cluster, for your own protection Ozone will refuse to work.</p> |
| |
| <p>In other words, till Ozone security work is done, Ozone will not work in any |
| secure clusters.</p> |
| |
| <p>The container manager part of Ozone runs inside DataNodes as a pluggable module. |
| To activate ozone you should define the service plugin implementation class.</p> |
| |
| <div class="alert alert-warning" role="alert"> |
| <b>Important</b>: It should be added to the <b>hdfs-site.xml</b> as the plugin should |
| be activated as part of the normal HDFS Datanode bootstrap. |
| </div> |
| |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-xml" data-lang="xml"><span style="color:#f92672"><property></span> |
| <span style="color:#f92672"><name></span>dfs.datanode.plugins<span style="color:#f92672"></name></span> |
| <span style="color:#f92672"><value></span>org.apache.hadoop.ozone.HddsDatanodeService<span style="color:#f92672"></value></span> |
| <span style="color:#f92672"></property></span></code></pre></div> |
| |
| <p>You also need to add the ozone-datanode-plugin jar file to the classpath:</p> |
| |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">export HADOOP_CLASSPATH<span style="color:#f92672">=</span>/opt/ozone/share/hadoop/ozoneplugin/hadoop-ozone-datanode-plugin.jar</code></pre></div> |
| |
| <p>To start ozone with HDFS you should start the the following components:</p> |
| |
| <ol> |
| <li>HDFS Namenode (from Hadoop distribution)</li> |
| <li>HDFS Datanode (from the Hadoop distribution with the plugin on the |
| classpath from the Ozone distribution)</li> |
| <li>Ozone Manager (from the Ozone distribution)</li> |
| <li>Storage Container manager (from the Ozone distribution)</li> |
| </ol> |
| |
| <p>Please check the log of the datanode whether the HDDS/Ozone plugin is started or |
| not. Log of datanode should contain something like this:</p> |
| |
| <pre><code>2018-09-17 16:19:24 INFO HddsDatanodeService:158 - Started plug-in org.apache.hadoop.ozone.web.OzoneHddsDatanodeService@6f94fb9d |
| </code></pre> |
| |
| <div class="alert alert-warning" role="alert"> |
| <b>Note:</b> The current version of Ozone is tested with Hadoop 3.1. |
