Rohith Sharma K S commented on YARN-4479:
-----------------------------------------
bq. I think we still need to treat ordering policy of pending apps specially,
and with the new added FifoOrderingPolicyForPendingApps, we don't need to reset
isRecoverying and other ordering policies don't need the isRecoverying field,
so it won't affect performance.
+1 for the approach, makesense to me
> Retrospect app-priority in pendingOrderingPolicy during recovering

> Currently, same ordering policy is used for pending applications and active
> applications. When priority is configured for an applications, during
> recovery high priority application get activated first. It is possible that
> low priority job was submitted and running state.
> This causes low priority job in starvation after recovery
