-------------------------------------

             Summary: A DStream that is checkpointed should allow its parent(s) to be removed and not persisted
                 Key: SPARK-25303
                 URL: https://issues.apache.org/jira/browse/SPARK-25303
             Project: Spark
          Issue Type: Bug
          Components: DStreams
    Affects Versions: 2.3.1, 2.3.0, 2.2.2, 2.2.1, 2.2.0, 2.1.3, 2.1.2, 2.1.1, 2.1.0, 2.0.2, 2.0.1, 2.0.0
            Reporter: Nikunj Bansal


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.
