title: What is JavaRDD[(Int, String)]?
body: <p>I am using Scala code in my Java App. I have seen return type of one method is <code>JavaRDD[(Int, String)]</code>. I do not understand what exactly this will translate to.</p>
  
  <p>For example, <code>JavaRDD[Int]</code> is equivalent to <code>JavaRDD&lt;Integer&gt;</code> in Java</p>
