>
> The Fair Scheduler never cleans up queues even if they are deleted in the allocation
file, or were dynamically created and are never going to be used again. Queues always remain
in memory which leads to two following issues.
>  # Steady fairshares aren’t calculated correctly due to remaining queues
>  # WebUI shows deleted queues, which is confusing for users (YARN-4022).
> We want to support proper queue deletion without restarting the Resource Manager:
>  # Static queues without any entries that are removed from fair-scheduler.xml should
be deleted from memory.
>  # Dynamic queues without any entries should be deleted.
>  # RM Web UI should only show the queues defined in the scheduler at that point in time.
