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

             Summary: Not properly cleaning PendingCheckpoints up
                 Key: FLINK-5660
                 URL: https://issues.apache.org/jira/browse/FLINK-5660
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.2.0, 1.3.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.3.0, 1.2.1


When cleaning up a {{PendingCheckpoint}}, then it sometimes happens that not all state handles are properly discarded. The reason is that the discard operation is executed asynchronously but the synchronous {{discard}} call already cleans the task state collection.
