title: How to get element by Index in Spark RDD (Java)
body: <p>I know the method rdd.firstwfirst() which gives me the first element in an RDD.</p>
  <p>Also there is the method rdd.take(num) Which gives me the first &quot;num&quot; elements.</p>
  <p>But isn't there a possibility to get an element by index?</p>
  <p>Thanks.e</p>
