Steve Loughran commented on YARN-2934:
--------------------------------------

good first pass.

I wouldn't worry about a configurable size for now (who gets to configure it?), 
but I would derive the text "4k bytes" from the string constant, instead of 
duplicate

needs a test; some minicluster one will suffice

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