There are a few things to keep in mind when using Spark +with these distributions:</p> + +<h1 id="compile-time-hadoop-version">Compile-time Hadoop Version</h1> + +<p>When compiling Spark, you’ll need to specify the Hadoop version by defining the <code>hadoop.version</code> +property. For certain versions, you will need to specify additional profiles. For more detail, +see the guide on <a href="building-spark.html#specifying-the-hadoop-version">building with maven</a>:</p> + +<pre><code>mvn -Dhadoop.version=1.0.4 -DskipTests clean package +mvn -Phadoop-2.3 -Dhadoop.version=2.3.0 -DskipTests clean package +</code></pre> + +<p>The table below lists the corresponding <code>hadoop.version</code> code for each CDH/HDP release. Note that +some Hadoop releases are binary compatible across client versions. This means the pre-built Spark +distribution may “just work” without you needing to compile. That said, we recommend compiling with +the <em>exact</em> Hadoop version you are running to avoid any compatibility errors.</p> + +<table> + <tr valign="top"> + <td> + <h3>CDH Releases</h3> + <table class="table" style="width:350px; margin-right: 20px;"> + <tr><th>Release</th><th>Version code</th></tr> + <tr><td>CDH 4.X.X (YARN mode)</td><td>2.0.0-cdh4.X.X</td></tr> + <tr><td>CDH 4.X.X</td><td>2.0.0-mr1-cdh4.X.X</td></tr> + </table> + </td> + <td> + <h3>HDP Releases</h3> + <table class="table" style="width:350px;"> + <tr><th>Release</th><th>Version code</th></tr> + <tr><td>HDP 1.3</td><td>1.2.0</td></tr> + <tr><td>HDP 1.2</td><td>1.1.2</td></tr> + <tr><td>HDP 1.1</td><td>1.0.3</td></tr> + <tr><td>HDP 1.0</td><td>1.0.3</td></tr> + <tr><td>HDP 2.0</td><td>2.2.0</td></tr> + </table> + </td> + </tr> +</table> + +<p>In SBT, the equivalent can be achieved by setting the the <code>hadoop.version</code> property:</p> + +<pre><code>build/sbt -Dhadoop.version=1.0.4 assembly +</code></pre> + +<h1 id="linking-applications-to-the-hadoop-version">Linking Applications to the Hadoop Version</h1> + +<p>In addition to compiling Spark itself against the right version, you need to add a Maven dependency on that +version of <code>hadoop-client</code> to any Spark applications you run, so they can also talk to the HDFS version +on the cluster. If you are using CDH, you also need to add the Cloudera Maven repository. +This looks as follows in SBT:</p> + +<div class="highlight"><pre><code class="language-scala" data-lang="scala"><span class="n">libraryDependencies</span> <span class="o">+=</span> <span class="s">"org.apache.hadoop"</span> <span class="o">%</span> <span class="s">"hadoop-client"</span> <span class="o">%</span> <span class="s">"<version>"</span> + +<span class="c1">// If using CDH, also add Cloudera repo</span> +<span class="n">resolvers</span> <span class="o">+=</span> <span class="s">"Cloudera Repository"</span> <span class="n">at</span> <span class="s">"https://repository.cloudera.com/artifactory/cloudera-repos/"</span></code></pre></div> + +<p>Or in Maven:</p> + +<div class="highlight"><pre><code class="language-xml" data-lang="xml"><span class="nt"><project></span> + <span class="nt"><dependencies></span> + ... + <span class="nt"><dependency></span> + <span class="nt"><groupId></span>org.apache.hadoop<span class="nt"></groupId></span> + <span class="nt"><artifactId></span>hadoop-client<span class="nt"></artifactId></span> + <span class="nt"><version></span>[version]<span class="nt"></version></span> + <span class="nt"></dependency></span> + <span class="nt"></dependencies></span> + + <span class="c"><!-- If using CDH, also add Cloudera repo --></span> + <span class="nt"><repositories></span> + ... + <span class="nt"><repository></span> + <span class="nt"><id></span>Cloudera repository<span class="nt"></id></span> + <span class="nt"><url></span>https://repository.cloudera.com/artifactory/cloudera-repos/<span class="nt"></url></span> + <span class="nt"></repository></span> + <span class="nt"></repositories></span> +<span class="nt"></project></span></code></pre></div> + +<h1 id="where-to-run-spark">Where to Run Spark</h1> + +<p>As described in the <a href="hardware-provisioning.html#storage-systems">Hardware Provisioning</a> guide, +Spark can run in a variety of deployment modes:</p> + +<ul> + <li>Using dedicated set of Spark nodes in your cluster. These nodes should be co-located with your +Hadoop installation.</li> + <li>Running on the same nodes as an existing Hadoop installation, with a fixed amount memory and +cores dedicated to Spark on each node.</li> + <li>Run Spark alongside Hadoop using a cluster resource manager, such as YARN or Mesos.</li> +</ul> + +<p>These options are identical for those using CDH and HDP.</p> + +<h1 id="inheriting-cluster-configuration">Inheriting Cluster Configuration</h1> + +<p>If you plan to read and write from HDFS using Spark, there are two Hadoop configuration files that +should be included on Spark’s classpath:</p> + +<ul> + <li><code>hdfs-site.xml</code>, which provides default behaviors for the HDFS client.</li> + <li><code>core-site.xml</code>, which sets the default filesystem name.</li> +</ul> + +<p>The location of these configuration files varies across CDH and HDP versions, but +a common location is inside of <code>/etc/hadoop/conf</code>.
