title: "Prefix not Found" and HiveConf ClassNotFoundException on Zeppelin Tutorial
body: <p>I am attempting to run the preinstalled <code>Zeppelin Tutorial</code>. None of the <code>%sql</code> or <code>%r</code> entries work: they all say either <strong><em>Prefix not Found</em></strong> or throw `java.lang.ClassNotFoundException: org.apache.hadoop.hive.conf.HiveConf</p>
  
  <p><code>%sql</code> broken: </p>

  <p><code>%R</code> broken: </p>

  <p>These errors happen for untouched / clean install Zeppelin. They continue to happen even after I pointed to a separate <code>spark</code> installation that I know contains hive.  Anyone figure these things out?</p>
