Li Lu commented on YARN-3390:
-----------------------------
Hi [~zjshen], the latest patch looks good to me. Just one note is that we need
to be careful when overriding the {{postRemove}} method. Since it's in a
synchronized block, having a long postRemove method may significantly blocks
the critical section.
I'm OK with all the rationales about the unfixed comments.
