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

             Summary: CheckpointCoordinator triggers checkpoints even if not all sources are running any more
                 Key: FLINK-2515
                 URL: https://issues.apache.org/jira/browse/FLINK-2515
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 0.10
            Reporter: Stephan Ewen
            Priority: Blocker
             Fix For: 0.10


When some sources finish early, they will not emit checkpoint barriers any more. That means that pending checkpoint alignments will never be able to complete, locking the flow.
