> This serves as an umbrella ticket for tasks related to better queue management in YARN.
> Today's the only way to manage the queue is through admins editing configuration files
and then issuing a refresh command. This will bring many inconveniences. For example, the
users can not create / delete /modify their own queues without talking to site level admins.
> Even in today's approach (configuration-based), we still have several places needed to
improve: 
> *  It is possible today to add or modify queues without restarting the RM, via a CS refresh.
But for deleting queue, we have to restart the resourcemanager.
> * When a queue is STOPPED, resources allocated to the queue can be handled better. Currently,
they'll only be used if the other queues are setup to go over their capacity.
