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

             Summary: TaskExecutor should filter out duplicate JobManager gained leadership messages
                 Key: FLINK-7526
                 URL: https://issues.apache.org/jira/browse/FLINK-7526
             Project: Flink
          Issue Type: Bug
          Components: Distributed Coordination
    Affects Versions: 1.4.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
            Priority: Minor


Currently, the {{TaskExecutor}} does not filter out duplicate JobManager gained leadership messages. This causes that multiple {{JobManagerConnections}} are opened which are not properly closed. In order to solve the problem, we should filter out duplicate messages wrt the leader session id.
