Varun Saxena commented on YARN-3142:
------------------------------------
Primarily converted synchronized methods to having code in methods inside RW
locks. Bits of some methods can potentially be outside critical section but as
I am not sure how much performance gain that would bring, I avoided adding
multiple try-finally constructs in the same method, for the sake of simplicity.
Haven't added any fine grained locking.
