title: How to connect Zeppelin to Spark 1.5 built from the sources?
body: <p>I pulled the latest source from the Spark repository and built locally. It works great from an interactive shell like <code>spark-shell</code> or <code>spark-sql</code>.</p>
  
  <p>Now I want to connect Zeppelin to my Spark 1.5, according to <a href="https://zeppelin.incubator.apache.org/docs/install/install.html">this install manual</a>. I published the custom Spark build to the local maven repository and set the custom Spark version in the Zeppelin build command. The build process finished successfully but when I try to run basic things like <code>sc</code> inside notebook, it throws:</p>
  
  <blockquote>
    <p>akka.ConfigurationException: Akka JAR version [2.3.11] does not match the provided config version [2.3.4]</p>
  </blockquote>
  
  <p>Version 2.3.4 is set in <code>pom.xml</code> and <code>spark/pom.xml</code>, but simply changing them won’t even let me get a build.</p>
  
  <p>If I rebuild Zeppelin with the standard <code>-Dspark.vesion=1.4.1</code>, everything works.</p>
