Carlo Curino commented on YARN-3973:
------------------------------------
[~leftnoteasy] what you propose makes more sense. From a quick test on actual
cluster, it looks like it works.
The problem during application submission is in fact not addressed by
overriding just in ReservationQueue,
ParentQueue must also provide an implementation (due to the reservation
mechanics for app submission),
thus doing this in AbstractCSQueue seems the right way.
I uploaded a simple patch for this, but please double check this carefully (I
am not familiar with priority mechanics).
