Till Rohrmann commented on FLINK-19037:
---------------------------------------
The same actually applies for the {{ResourceManager}} as well. One idea could
be to forward the {{ClusterEntrypoint.ioExecutor}} to the
{{DispatcherResourceManagerComponent}} and then farther to the {{Dispatcher}}
and {{ResourceManager}}.
> Introduce proper IO executor in Dispatcher
