Firstly Thanks for the work!
i have one question?, does it support getPersistentRDDs ? use case is
reusing cached rdd, something along line of spark job server
```
scala> sc.getPersistentRDDs.values.head
res1: org.apache.spark.rdd.RDD[_] = MapPartitionsRDD[2] at apply at
<console>:15
scala> val getrdd =
sc.getPersistentRDDs.values.head.asInstanceOf[org.apache.spark.rdd.IndexedRDD[Int]]
java.lang.ClassCastException: org.apache.spark.rdd.MapPartitionsRDD cannot
be cast to org.apache.spark.rdd.IndexedRDD
