Arun Suresh commented on YARN-7676:
-----------------------------------
Thanks for raising this Botong.
[~leftnoteasy] / [~sunilg] will this affect application priority (ordering of
the apps itself) ? Looking at {{TestApplicationPriority}} am guessing it would.
> Fix inconsistent priority ordering in Priority and SchedulerRequestKey

> Today the priority ordering in _Priority.compareTo()_ and
> _SchedulerRequestKey.compareTo()_ is inconsistent. Both _compareTo_ method is
> trying to reverse the order:
> P0.compareTo(P1) > 0, meaning priority wise P0 < P1. However,
> SK(P0).comapreTo(SK(P1)) < 0, meaning priority wise SK(P0) > SK(P1).
> This is attempting to fix that by undo both reversing logic. So that priority
> wise P0 > P1 and SK(P0) > SK(P1).
