Varun Saxena commented on YARN-3045:
------------------------------------

[~Naganarasimha], a couple of comments.

# In NMTimelinePublisher, we can make Container***Event classes as private. I 
do not see them being referenced anywhere else
# Will a single event queue with a single event handling thread in async 
dispatcher be enough to handle container events ? I think they may be too many.
