Craig Welch commented on YARN-2644:
-----------------------------------
Just putting our offline discussion here - the headRoomProvider has application
specific info, so it can't go on the queue (the user and the required fields)
> 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.
