> 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
