>
> The current {{JobManager}} registration at the {{ResourceManager}} blocks
> threads in the {{RpcService.execute}} pool. This is not ideal and can be
> avoided by not waiting on a {{Future}} in this call.
> I propose to encapsulate the leader id retrieval operation in a distinct
> service so that it can be separated from the {{ResourceManager}}. This will
> reduce the complexity of the {{ResourceManager}} and make the individual
> components easier to test.
