> The question "which apps are in queue x" can be asked via the RM REST APIs,
> through the ClientRMService, and through the command line. In all these
> cases, the question is answered by scanning through every RMApp and filtering
> by the app's queue name.
> All schedulers maintain a mapping of queues to applications. I think it
> would make more sense to ask the schedulers which applications are in a given
> queue. This is what was done in MR1. This would also have the advantage of
> allowing a parent queue to return all the applications on leaf queues under
> it, and allow queue name aliases, as in the way that "root.default" and
> "default" refer to the same queue in the fair scheduler.
