[jira] [Created] (SPARK-30502) PeriodicRDDCheckpointer & PeriodicGraphCheckpointer add storageLevel

zhengruifeng created SPARK-30502:
------------------------------------

             Summary: PeriodicRDDCheckpointer & PeriodicGraphCheckpointer add storageLevel
                 Key: SPARK-30502
                 URL: https://issues.apache.org/jira/browse/SPARK-30502
             Project: Spark
          Issue Type: Improvement
          Components: GraphX, ML, Spark Core
    Affects Versions: 3.0.0
            Reporter: zhengruifeng


Intermediate RDDs in ML are cached with storageLevel=StorageLevel.MEMORY_AND_DISK.

PeriodicRDDCheckpointer & PeriodicGraphCheckpointer will store RDD with storageLevel=StorageLevel.MEMORY_ONLY, it maybe nice to set the storageLevel of checkpointer.
