------------------------------
Resolution: Duplicate
> Grant leadership to leaderContender while it is closing may lead to deadlock
> ----------------------------------------------------------------------------
>
> Key: FLINK-29808
> URL: https://issues.apache.org/jira/browse/FLINK-29808
> Project: Flink
> Issue Type: Technical Debt
> Components: Runtime / Coordination
> Affects Versions: 1.17.0
> Reporter: Weijie Guo
> Priority: Major
>
> If we grant leadership to a leaderContender, but it is closing at the same
> time, deadlock may occur. This phenomenon was observed in
> 'JobMasterServiceLeadershipRunner'. Through some investigation, I found that
> `ResourceManagerServiceImpl` took some measures to avoid this problem, and
> FLINK-29234 try to fix this problem in a similar way.
> However, there are other implementations of leaderContender. We need to check
> the code and introduce some tests when necessary to ensure that they will not
> suffer the same problem.
