Wangda Tan commented on YARN-3873:
----------------------------------
Hi [~sunilg],
Sorry for confusing you in my last comment, what I meant is not hard code
FifoOrderingPolicy for ALL policies, what I meant is to use the same
OrderingPolicy for pendingApplications. For example, when policy=fair,
pendingApps & runningApps use FairOrderingPolicy, when policy=fifo, pendingApps
& runningApps use FifoOrderingPolicy.
Thoughts?
> pendingApplications in LeafQueue should also use OrderingPolicy

> pendingApplications can use the OrderingPolicy configured in Queue level
