Sunil G commented on YARN-1963:
-------------------------------
Thank you [~vinodkv] and [~nroberts] for the comments.
Considering usability ways, labels will be handy. And scheduler must be
agnostic of labels and should handle only integers like in linux. This will
have a complexity on priority manager inside RM which will translate label ->
integer an vice versa. But a call can be taken by seeing all possibilities and
can be standardized the same so that a minimal working version can be pushed in
by improvising on the patches submitted (working prototype was attached).
Hoping [~leftnoteasy] and [~eepayne] to join the discussion.

> 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.
