      Description

      A checkpointed DStream is supposed to cut the lineage to its parent(s) such that any persisted RDDs for the parent(s) are removed. However, combined with the issue in SPARK-25302, they result in the Input Stream RDDs being persisted a lot longer than they are actually required.
