Gera Shegalov commented on YARN-2934:
-------------------------------------
Regarding my comment about the user, I meant the YARN app user. The users don't
look at the NM logs. They look at the exceptions in the webUI and on the client
side. if the exception says
{code}
Container exited with a non-zero exit code 127. Error file(s): [error.log,
stderr.1, stderr.2]
Last 4096 bytes of error.log :
/bin/bash: /no/jvm/here/bin/java: No such file or directory
{code}
the user will know it should also check those.
> 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.
