          I'm thinking we don't need the synchronization in collectSchedulerApplications, and it's better to use read-write lock for performance. You can use the latest patch in YARN-2910 as reference.

          Thanks Akira Ajisaka for reviewing patch.
          I'd prefer to use synchronization rather than using read-write lock mechanism. In LeafQueue, pendingApplications and activeApplications are synchronized on this in all the methods. There must be consistency lock acros LeafQueue. If I see FSLeafQueue, runningApps and nonrunningApps were not synchronized before. So, it is best approach to use read-write lock in FSLeafQueue.

          Akira Ajisaka it's not for performance but for avoiding deadlock essentially about FSLeafQueue on YARN-2910.

          looks like LeafQueue#getTotalResourcePending should be changed too. does it make sense to synchronize on the object itself ?

          You are right, it is possible to ocure ConcurrentModificatinException since LeafQueue#getTotalResourcePending is public interface.

          Updated the patch for the same, kindly review
