-------------------------------------
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.
