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
> Improve handling of container's stderr
