Craig Welch commented on YARN-3318:
-----------------------------------
The proposed initial implementation of the framework to support FIFO
SchedulerApplicationAttempt ordering for the CapacityScheduler:
A SchedulerComparatorPolicy which implements OrderingPolicy above. This
implementation will take care of the common logic required for cases where the
policy can be effectively implemented as a comparator (which is expected to be
the case for several potential policies, including FIFO).
A SchedulerComparator which is used by the SchedulerComparatorPolicy above.
This is an extension of the java Comparator interface with additional logic
required by the SchedulerComparatorPolicy, initially a method to accept
SchedulerProcessEvents and indicate whether the require re-ordering of the
associated SchedulerProcess.
