title: importing pyspark in python shell
body: <p><em>This is a copy of someone else's question on another forum that was never answered, so I thought I'd re-ask it here, as I have the same issue.  (See <a href="http://geekple.com/blogs/feeds/Xgzu7/posts/351703064084736">http://geekple.com/blogs/feeds/Xgzu7/posts/351703064084736</a>)</em></p>
  
  <p>I have Spark installed properly on my machine and am able to run python programs with the pyspark modules without error when using ./bin/pyspark as my python interpreter.</p>
  
  <p>However, when I attempt to run the regular Python shell, when I try to import pyspark modules I get this error:</p>
  
  <pre><code>from pyspark import SparkContext
  </code></pre>
  
  <p>and it says</p>
  
  <pre><code>"No module named pyspark".
  </code></pre>
  
  <p>How can I fix this?  Is there an environment variable I need to set to point Python to the pyspark headers/libraries/etc.?  If my spark installation is /spark/, which pyspark paths do I need to include?  Or can pyspark programs only be run from the pyspark interpreter?</p>
