title: Transform Java-Pair-Rdd to Rdd
body: <p>I need to transform my Java-pair-rdd to a csv :</p>
  <p>so i m thinking to transform it to rdd, to solve my problem.</p>
  <p>what i want is to have my rdd transformed
  from :</p>
  <pre><code>Key   Value
  Jack  [a,b,c]
  </code></pre>
  <p>to :</p>
  <pre><code>Key  value
  Jack  a
  Jack  b
  Jack  c
  </code></pre>
  <p>i see that it is possible in that <a href="https://stackoverflow.com/questions/39504400/load-spark-rdd-to-neo4j-in-python?noredirect=1#comment89507177_39504400">issue</a> and in this issue(<a href="https://stackoverflow.com/questions/32971315/pyspark-convert-a-pair-rdd-back-to-a-regular-rdd/32975221#comment89543754_32975221">PySpark: Convert a pair RDD back to a regular RDD</a>)
  so  i am asking how to do that in java?</p>
  <h1>Update of question</h1>
  <p>The Type of my <em>JavaPairRdd</em> is of Type :</p>
  <pre><code>JavaPairRDD&lt;Tuple2&lt;String,String&gt;, Iterable&lt;Tuple1&lt;String&gt;&gt;&gt;
  </code></pre>
  <p>and this is the form of row that contain :</p>
  <pre><code>((dr5rvey,dr5ruku),[(2,01/09/2013 00:09,01/09/2013 00:27,N,1,-73.9287262,40.75831223,-73.98726654,40.76442719,2,3.96,16,0.5,0.5,4.25,0,,21.25,1,)])
  </code></pre>
  <p>the <strong>key</strong> here is : <code>(dr5rvey,dr5ruku)</code> and the <strong>value</strong> is <code>[(2,01/09/2013 00:09,01/09/2013 00:27,N,1,-73.9287262,40.75831223,-73.98726654,40.76442719,2,3.96,16,0.5,0.5,4.25,0,,21.25,1,)]</code></p>
  <p>my original <em>JavaRdd</em> was of type:</p>
  <pre><code>JavaRDD&lt;String&gt;
  </code></pre>
