> Currently, {{DefaultLeaderElectionService}} logs leadership changing events in DEBUG level, expecting the contender to log the changes in INFO level. This is fragile because there're many different {{LeaderContender}} implementations and not all of them print the logs properly. E.g., {{JobMasterServiceLeadershipRunner}} logs the leadership changes in TRACE level.
> I'd suggest to revisit the logging of leadership changing, printing the INFO logs from {{LeaderElectionService}}. That probably also means removing the contender side logs to avoid redundancy.
