> The current implementations of {{LeaderElectionService}} do not implement the
> {{stop()}} call consistently. Some (e.g.
> [StandaloneLeaderElectionService|https://github.com/apache/flink/blob/c6997c97c575d334679915c328792b8a3067cfb5/flink-runtime/src/main/java/org/apache/flink/runtime/leaderelection/StandaloneLeaderElectionService.java#L53]
> call revoke on the {{LeaderContender)}} whereas others don't (e.g.
> [DefaultLeaderElectionService|https://github.com/apache/flink/blob/6e1caa390882996bf2d602951b54e4bb2d9c90dc/flink-runtime/src/main/java/org/apache/flink/runtime/leaderelection/DefaultLeaderElectionService.java#L96]).
> The
> [MultipleComponentLeaderElectionService|https://github.com/apache/flink/blob/0290715a57b8d243586ab747b0cd2416c8081012/flink-runtime/src/main/java/org/apache/flink/runtime/leaderelection/DefaultMultipleComponentLeaderElectionService.java#L166]
> 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).
