Ravi Prakash commented on YARN-1963:
------------------------------------
I wonder if it'd be a good idea to percolate the priorities onto the actual
containers as well? (I'm thinking (re)nice-ing container processes) ? That way
we can submit more jobs than can all fit into memory and take advantage of OS
scheduling to pick up the ones with the highest priority?

> 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.
