Eric Payne commented on YARN-1963:
----------------------------------

{quote}
I think label-based and integer-based priorities are just two different ways to 
configure as well as API. No matter we choose to use label-based or 
integer-based priority, we should use integer only to implement internal logic 
(like in CapacityScheduler).
{quote}
I think that is true especially when passing priorities through proto buffers, 
using integers is best.

> Support priorities across applications within the same queue

> 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.
