Vinod Kumar Vavilapalli commented on YARN-1545:

I covered the details on the individual tickets - it's mostly about bounding 
buffers, lists etc.

When I filed this I was only focusing on application level stuff. A bad client 
firing off RPCs in rapid fire can and should be addressed at in the RPC layer 
itself IMO.
