> Key: FLINK-24038
> URL: https://issues.apache.org/jira/browse/FLINK-24038
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.14.0
> Reporter: Till Rohrmann
> Priority: Critical
> Fix For: 1.14.0

>
> With FLINK-21667 we introduced a change that can cause the
> {{DispatcherResourceManagerComponent}} to fail when trying to stop the
> application. The problem is that the {{DispatcherResourceManagerComponent}}
> needs a leading {{ResourceManager}} to successfully execute the
> stop/deregister application call. If this is not the case, then it will fail
> fatally. In the case of multiple standby JobManager processes it can happen
> that the leading {{ResourceManager}} runs somewhere else.
> I do see two possible solutions:
> 1. Run the leader election process for the whole JobManager process
> 2. Move the registration/deregistration of the application out of the
> {{ResourceManager}} so that it can be executed w/o a leader
