newer and Java 6+.</p> + +<p><strong>Note:</strong> Building Spark with Java 7 or later can create JAR files that may not be +readable with early versions of Java 6, due to the large number of files in the JAR +archive. Build with Java 6 if this is an issue for your deployment.</p> + +<h1 id="building-with-buildmvn">Building with <code>build/mvn</code></h1> + +<p>Spark now comes packaged with a self-contained Maven installation to ease building and deployment of Spark from source located under the <code>build/</code> directory. This script will automatically download and setup all necessary build requirements (<a href="https://maven.apache.org/">Maven</a>, <a href="http://www.scala-lang.org/">Scala</a>, and <a href="https://github.com/typesafehub/zinc">Zinc</a>) locally within the <code>build/</code> directory itself. It honors any <code>mvn</code> binary if present already, however, will pull down its own copy of Scala and Zinc regardless to ensure proper version requirements are met. <code>build/mvn</code> execution acts as a pass through to the <code>mvn</code> call allowing easy transition from previous build methods. As an example, one can build a version of Spark as follows:</p> + +<div class="highlight"><pre><code class="language-bash" data-lang="bash">build/mvn -Pyarn -Phadoop-2.4 -Dhadoop.version<span class="o">=</span>2.4.0 -DskipTests clean package</code></pre></div> + +<p>Other build examples can be found below.</p> + +<p><strong>Note:</strong> When building on an encrypted filesystem (if your home directory is encrypted, for example), then the Spark build might fail with a “Filename too long” error. As a workaround, add the following in the configuration args of the <code>scala-maven-plugin</code> in the project <code>pom.xml</code>:</p> + +<pre><code><arg>-Xmax-classfile-name</arg> +<arg>128</arg> +</code></pre> + +<p>and in <code>project/SparkBuild.scala</code> add:</p> + +<pre><code>scalacOptions in Compile ++= Seq("-Xmax-classfile-name", "128"), +</code></pre> + +<p>to the <code>sharedSettings</code> val. See also <a href="https://github.com/apache/spark/pull/2883/files">this PR</a> if you are unsure of where to add these lines.</p> + +<h1 id="building-a-runnable-distribution">Building a Runnable Distribution</h1> + +<p>To create a Spark distribution like those distributed by the +<a href="http://spark.apache.org/downloads.html">Spark Downloads</a> page, and that is laid out so as +to be runnable, use <code>make-distribution.sh</code> in the project root directory.

You can do this through the “hadoop.version” property. If unset, Spark will build against Hadoop 2.2.0 by default.

A couple of gotchas to note:</p> + +<ul> + <li> + <p>it only scans the paths <code>src/main</code> and <code>src/test</code> (see +<a href="http://scala-tools.org/mvnsites/maven-scala-plugin/usage_cc.html">docs</a>), so it will only work +from within certain submodules that have that structure.</p> + </li> + <li> + <p>you’ll typically need to run <code>mvn install</code> from the project root for compilation within +specific submodules to work; this is because submodules that depend on other submodules do so via +the <code>spark-parent</code> module).</p> + </li> +</ul> + +<p>Thus, the full flow for running continuous-compilation of the <code>core</code> submodule may look more like:</p> + +<p><code> + $ mvn install + $ cd core + $ mvn scala:cc +</code></p> + +<h1 id="building-spark-with-intellij-idea-or-eclipse">Building Spark with IntelliJ IDEA or Eclipse</h1> + +<p>For help in setting up IntelliJ IDEA or Eclipse for Spark development, and troubleshooting, refer to the +<a href="https://cwiki.apache.org/confluence/display/SPARK/Useful+Developer+Tools#UsefulDeveloperTools-IDESetup">wiki page for IDE setup</a>.</p> + +<h1 id="running-java-8-test-suites">Running Java 8 Test Suites</h1> + +<p>Running only Java 8 tests and nothing else.</p> + +<pre><code>mvn install -DskipTests -Pjava8-tests +</code></pre> + +<p>Java 8 tests are run when <code>-Pjava8-tests</code> profile is enabled, they will run in spite of <code>-DskipTests</code>. +For these tests to run your system must have a JDK 8 installation. +If you have JDK 8 installed but it is not the system default, you can set JAVA_HOME to point to JDK 8 before running the tests.</p> + +<h1 id="building-for-pyspark-on-yarn">Building for PySpark on YARN</h1> + +<p>PySpark on YARN is only supported if the jar is built with Maven. Further, there is a known problem +with building this assembly jar on Red Hat based operating systems (see <a href="https://issues.apache.org/jira/browse/SPARK-1753">SPARK-1753</a>). If you wish to +run PySpark on a YARN cluster with Red Hat installed, we recommend that you build the jar elsewhere, +then ship it over to the cluster. We are investigating the exact cause for this.</p> + +<h1 id="packaging-without-hadoop-dependencies-for-yarn">Packaging without Hadoop Dependencies for YARN</h1> + +<p>The assembly jar produced by <code>mvn package</code> will, by default, include all of Spark’s dependencies, including Hadoop and some of its ecosystem projects. On YARN deployments, this causes multiple versions of these to appear on executor classpaths: the version packaged in the Spark assembly and the version on each node, included with yarn.application.classpath. The <code>hadoop-provided</code> profile builds the assembly without including Hadoop-ecosystem projects, like ZooKeeper and Hadoop itself.</p> + +<h1 id="building-with-sbt">Building with SBT</h1> + +<p>Maven is the official recommendation for packaging Spark, and is the “build of reference”. +But SBT is supported for day-to-day development since it can provide much faster iterative +compilation. More advanced developers may wish to use SBT.</p> + +<p>The SBT build is derived from the Maven POM files, and so the same Maven profiles and variables +can be set to control the SBT build. For example:</p> + +<pre><code>build/sbt -Pyarn -Phadoop-2.3 assembly +</code></pre> + +<h1 id="testing-with-sbt">Testing with SBT</h1> + +<p>Some of the tests require Spark to be packaged first, so always run <code>build/sbt assembly</code> the first time.
