Gera Shegalov commented on YARN-2934:
-------------------------------------
Minor repetition is not big of a deal, IMO.
The reason I thought of printing file statuses is that you see the file size.
Which brings us to the following point in the fanciness area. Right now we are
blindly grabbing file 0. It would however make much more sense to grab the most
recent (highest mtime) non-empty file.
> Improve handling of container's stderr

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