Craig Welch commented on YARN-3319:
-----------------------------------
Initially this will be implemented for SchedulerApplicationAttempts in the
CapacityScheduler LeafQueue (similar to the FIFO implementation in
[YARN-3318]). The expectation is that this will be implement the
SchedulerComparator interface and will be used as a comparator within the
SchedulerComparatorPolicy implementation to achieve the intended behavior.
