> The "getPersistentRDDs()" is a useful API of SparkContext to get cached RDDs. However, the JavaSparkContext does not have this API. Though it is possible to first call "getPersistentRDDs: Map[Int, RDD[_]]", and then transfer to java.util.Map<Integer, JavaRDD>, it is easier to do the transform in scala and supply a clean Java API, especially for some JavaSparkContext users who are not familiar with scala.
