------------------------------------------
I have a solution, involving inserting a global flag in the JobMaster that I
would like to contribute. Can I please be assigned this issue?

> Key: FLINK-26773
> URL: https://issues.apache.org/jira/browse/FLINK-26773
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.15.0, 1.14.4, 1.16.0
> Reporter: Matthias Pohl

> There's a race condition happening with the {{ResourceManager}} leader
> election in the {{JobMaster}} while shutting it down. The {{JobMaster}} calls
> {{dissolveResourceManagerConnection}} while shutting down itself trying to
> disconnect itself from the {{ResourceManager}} (see
> [JobMaster:1180|https://github.com/apache/flink/blob/fdb80108a3c0e4fb12dbc3f89ecb2327d97deebf/flink-runtime/src/main/java/org/apache/flink/runtime/jobmaster/JobMaster.java#L1180]).
> This closes the RM connection to the {{JobMaster}} from the
> {{ResourceManager}}'s side (see
> [ResourceManager:979|https://github.com/apache/flink/blob/9055279d0286f4374694325250a45dc1c60301a7/flink-runtime/src/main/java/org/apache/flink/runtime/resourcemanager/ResourceManager.java#L979].
> The {{JobMaster}} tries to reconnect to the {{ResourceManager}} leader if
> there's still an address stored for that leader (which is the case during
> shutdown; see
> [JobMaster:790|https://github.com/apache/flink/blob/fdb80108a3c0e4fb12dbc3f89ecb2327d97deebf/flink-runtime/src/main/java/org/apache/flink/runtime/jobmaster/JobMaster.java#L790]).
> The {{JobMaster}} shouldn't try to reconnect after it has already freed it's
> requirements as part of the shutdown.
