Sunil G commented on YARN-1963:
-------------------------------

Thank you Wangda and [~eepayne] for the comments.

ACL, if configured for a queue, will be considered before submitting the job. If there are
no configuration, only queue ACL will be checked which is same as what is happening now. priority
label level ACL is on top of queue level ACL which is extra and can be configured as needed
by admin.

> It will be very useful to support priorities among applications within the same queue,
particularly in production scenarios. It allows for finer-grained controls without having
to force admins to create a multitude of queues, plus allows existing applications to continue
using existing queues which are usually part of institutional memory.
