Thank you [~botong] for updated patch

I should have excluded all apps that are still in YarnRM memory. That should
eliminate the race condition you mentioned. What do you think?

Yes , I agree with the same for fixing race.
One concern is the response size. Since all applications are fetched from
overall cluster.
we could be fetching at worst case 5k x subclusters applications.

> In Federation, we need a cleanup service for StateStore as well as Yarn
> Registry. For the former, we need to remove old application records. For the
> latter, failed and killed applications might leave records in the Yarn
> Registry (see YARN-6128). We plan to do both cleanup work in
> ApplicationCleaner in GPG
