title: Apache Zeppelin tutorial failing
body: <p>Recently I installed Zeppelin from git using  <code>mvn clean package -Pspark-1.5 -Dspark.version=1.5.1 -Phadoop-2.4 -Pyarn -Ppyspark -DskipTests</code> and I can't run the tutorial because of this error: </p>
  
  <pre><code>java.net.ConnectException
  </code></pre>
  
  <p>Any idea why this is happening? I haven't modified any of the conf files because I am interested in running it using the embedded Spark binaries.</p>
  
  <p>I already check most of the threads here and none of them has worked.</p>
  
  <p>Thanks</p>
  
  <p>EDIT: I am using a Mac</p>
