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 !

> Most YARN applications redirect stderr to some file. That's why when container launch
fails with {{ExitCodeException}} the message is empty.
