Sunil G updated YARN-3873:
--------------------------
Attachment: 0004-YARN-3873.patch
Updating patch after rebasing.
New api {{getActivateIterator}} in OrderingPolicy will be used to activate
application from pending list. For {{FiFoOrderingPolicy}}, it will be comparing
priority and timestamp. Also if we use {{FairOrderingPolicy}}
{{getActivateIterator}} alone, then it will compare applications with
priority/submitted timestamp. But if we use any other comparator, then order
will not be as expected.
[~leftnoteasy] could you please share your thoughts.
> pendingApplications in LeafQueue should also use OrderingPolicy
