title: Working with rdd
body: <p>I have a rdd </p>
  
  <pre><code>[u'1,0,0,0,0,0,0,0,1,2013,52,0,4,1,0',
   u'1,0,0,0,1,1,0,1,1,2012,49,1,1,0,1',
   u'1,0,0,0,1,1,0,0,1,2012,49,1,1,0,1',
   u'0,1,0,0,0,0,1,1,1,2014,45,0,0,1,0']
  </code></pre>
  
  <p>With this code </p>
  
  <pre><code>rdd = rdd.groupBy(lambda x: x.split(",")[9])
  new_rdds = [sc.parallelize(x[1]) for x in rdd.collect()]
  
  for x in new_rdds:
      print x.collect()
  </code></pre>
  
  <p>I got </p>
  
  <pre><code> [u'1,0,0,0,0,0,0,0,1,2013,52,0,4,1,0'],
   [u'1,0,0,0,1,1,0,1,1,2012,49,1,1,0,1',
    u'1,0,0,0,1,1,0,0,1,2012,49,1,1,0,1']
   [ u'0,1,0,0,0,0,1,1,1,2014,45,0,0,1,0']
  </code></pre>
  
  <p>Is there a way to get only a specific rdd , for example where x[9]=2014</p>
  
  <p>so I can get <pre>[u'0,1,0,0,0,0,1,1,1,2014,45,0,0,1,0']</pre></p>
