Naganarasimha G R updated YARN-2934:
------------------------------------
Attachment: YARN-2934.v2.004.patch
Thanks for the comments [~jira.shegalov],
bq. Things we have not addressed from my previous comments is capping the
buffer size.
Sorry for missing this comment out earlier but as you said its usually small
size and default is also small hence we can avoid it.
Have taken care of other comments in the uploaded patch, please review !
