Eric Payne commented on YARN-1963:

Thanks, [~sunilg], for your work on in-queue priorities.

Along with [~nroberts], I'm confused about why priority labels are needed. As a 
user, I just need to know that the higher the number, the higher the priority. 
Then, I just need a way to see what priority each application is using and a 
way to set the priority of applications. To me, it just seems like labels will 
get in the way.

> 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.
