[jira] [Created] (FLINK-23947) DefaultDispatcherRunner does not log when the Dispatcher gains and loses leadership

Till Rohrmann created FLINK-23947:
-------------------------------------

             Summary: DefaultDispatcherRunner does not log when the Dispatcher gains and loses leadership
                 Key: FLINK-23947
                 URL: https://issues.apache.org/jira/browse/FLINK-23947
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.13.2, 1.12.5, 1.14.0
            Reporter: Till Rohrmann
             Fix For: 1.14.0, 1.12.6, 1.13.3


The {{DefaultDispatcherRunner}} does not log when it gains and loses leadership. This can make it hard to understand the behaviour from Flink's logs because {{*DispatcherLeaderProcess}} can suddenly be stopped w/o knowing why. I suggest to improve the logging in the {{DefaultDispatcherRunner}} to make the logs easier to understand.
