pyspark interpreter not found in apache zeppelin
<p>I am having issue with using pyspark in Apache-Zeppelin (version 0.6.0) notebook. Running the following simple code gives me <code>pyspark interpreter not found</code> error</p>

<pre><code>%pyspark
a = 1+3
</code></pre>

<p>Running <code>sc.version</code> gave me <code>res2: String = 1.6.0</code> which is the version of spark installed on my machine. And running <code>z</code> return <code>res0: org.apache.zeppelin.spark.ZeppelinContext = {}</code></p>

<ol>
<li><p>Pyspark works from CLI (using spark 1.6.0 and python 2.6.6)</p></li>
<li><p>The default python on the machine 2.6.6, while anaconda-python 3.5 is also installed but not set as default python.</p></li>
<li><p>Based on this <a href="https://community.hortonworks.com/questions/16436/cants-get-pyspark-interpreter-to-work-on-zeppelin.html" rel="nofollow">post</a> I updated the zeppelin-env.sh file located at <code>/usr/hdp/current/zeppelin-server/lib/conf</code> and added Anaconda python 3 path </p></li>
</ol>

<blockquote>
<pre><code>export PYSPARK_PYTHON=/opt/anaconda3/bin/python
export PYTHONPATH=/opt/anaconda3/bin/python
</code></pre>
</blockquote>

<p>After that I have stopped and restarted zeppelin many times using </p>

<pre><code>/usr/hdp/current/zeppelin-server/lib/bin/zeppelin-daemon.sh
</code></pre>

<p>But I can't get the pyspark interpreter to work in zeppelin.</p>
