             Summary: Dispatcher fails to recover jobs if leader change happens during JobManagerRunner termination
                 Key: FLINK-11843
                 URL: https://issues.apache.org/jira/browse/FLINK-11843
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.7.2, 1.8.0
            Reporter: Till Rohrmann


The {{Dispatcher}} fails to recover jobs if a leader change happens during the {{JobManagerRunner}} termination of the previous run. The problem is that we schedule the start future of the recovered {{JobGraph}} using the {{MainThreadExecutor}} and additionally require that this future is completed before any other recovery operation from a subsequent leadership session is executed. If now the leadership changes, the {{MainThreadExecutor}} will be invalidated and the scheduled future will never be completed.
