------------------------------------
Summary: Add getPersistentRDDs() API to JavaSparkContext
Key: SPARK-13074
URL: https://issues.apache.org/jira/browse/SPARK-13074
Project: Spark
Issue Type: New Feature
Components: Spark Core
Reporter: Junyang Shen
Priority: Minor
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.
