Jian He commented on YARN-2644:
-------------------------------
Just one more thing:
- probably we can move {{headroomProvider}} field into LeafQueue. Update
headroomProvider info in the queue itself. {{FiCaSchedulerApp}} change can be
simplified, it can get the headroomProvider via the queue Reference.
> Recalculate headroom more frequently to keep it accurate

> See parent (1198) for more detail - this specifically covers calculating the
> headroom more frequently, to cover the cases where changes have occurred
> which impact headroom but which are not reflected due to an application not
> being updated.
