> When I delete an existing queue by modify the xxx-schedule.xml, I can still
> see the queue information block in webpage(/cluster/scheduler) though the
> 'Min Resources' items all become to zero and have no item of 'Max Running
> Applications'.
> I can still submit an application to the deleted queue and the application
> will run using 'root.default' queue instead, but submit to an un-exist queue
> will cause an exception.
> My expectation is the deleted queue will not displayed in webpage and submit
> application to the deleted queue will act just like the queue doesn't exist.
> PS: There's no application running in the queue I delete.
> Some related config in yarn-site.xml:
