Arun Suresh commented on YARN-5938:
-----------------------------------
The failed test case runs locally and the checkstyle warning fix would require
further refactoring of the {{ApplicationMasterService::allocateInternal()}}
method, which should probably tackled as a separate patch.

> Minor code re-organization to do the following:
> # The OpportunisticContainerAllocatorAMService currently allocates outside
> the ApplicationAttempt lock maintained by the ApplicationMasterService. This
> should happen inside the lock.
> # Refactored out some code to simplify the allocate() method.
> # Removed some unused fields inside the OpportunisticContainerAllocator.
> # Re-organized some of the code in the
> OpportunisticContainerAllocatorAMService::allocate method to make it a bit
> more readable.
> # Moved SchedulerRequestKey to a new package, so it can be used by the
> OpportunisticContainerAllocator/Context.
> # Moved all usages of Priority in the OpportunisticContainerAllocator ->
> SchedulerRequestKey.
