Xintong Song commented on FLINK-24038:
--------------------------------------
bq. For the new options #1 Xintong Song listed, do you mean let the leader
dispatcher do the deregistration? If it is, what will happen without leader.
Yes, I meant let the leading dispatcher to do the deregistration. According to
[~trohrmann], the decision whether to shut down the cluster or not is currently
made by the Dispatcher. IIUC, that means there should not be a shutdown without
a leading dispatcher, because there won't be any dispatcher to make that
decision without obtaining leadership.

> 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
