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

             Summary: Add task status reconciliation between TM and JM
                 Key: FLINK-17075
                 URL: https://issues.apache.org/jira/browse/FLINK-17075
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.10.0, 1.11.0
            Reporter: Till Rohrmann


In order to harden the TM and JM communication I suggest to let the {{TaskExecutor}} send the task statuses back to the {{JobMaster}} as part of the heartbeat payload (similar to FLINK-11059). This would allow to reconcile the states of both components in case that a status update message was lost as described by a user on the ML.
