Wei Yan commented on YARN-2099:
-------------------------------
Add a PriorityPolicy besides the existing fifo/fair/drf should work fine. Also,
we also need to think about the resource allocation part. For a queue using
PriorityPolicy, resource should be assigned to the applications from the
highest proority. right?
> Preemption in fair scheduler should consider app priorities
