Sunil G commented on YARN-1963:

Thank you [~devaraj.k] for input

I have updated the subjiras and uploaded patch by considering integer rather 
than label names.
As mentioned, we can have the enums supported from MR side (can try using 
enums). But a translation table is needed for same and its better keep the same 
YarnClient side.

> 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.
