Rohith Sharma K S commented on YARN-4479:
-----------------------------------------

I had 2 options in doing this in fifoordering policy. I took simpler approach to make working
patch. Further improvements like this will/can be addressed in coming patches once initial
approach is agreed upon.

> 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
