LeaderElectionService.stop should always call revokeLeadership

    XMLWordPrintableJSON

Details

    Description

      The current implementations of LeaderElectionService do not implement the stop() call consistently. Some (e.g. StandaloneLeaderElectionService call revoke on the LeaderContender) whereas others don't (e.g. DefaultLeaderElectionService). The MultipleComponentLeaderElectionService does call revoke on the LeaderContender instances, though.

      We should align this behavior and specify it in the LeaderElectionService contract before going ahead with refactoring the interfaces (FLIP-285).
