Manikandan R commented on YARN-10049:
-------------------------------------
Thanks [~sunilg] [~leftnoteasy]
Attaching .001.patch based on earlier discussions.
{{FIFOComparator}} has been used in FifoOrderingPolicy,
FifoOrderingPolicyForPendingApps, FifoOrderingPolicyWithExclusivePartitions
(through other class) and FairOrderingPolicy but in different order. So changes
made in comparator would be applicable in all above policies.
