Alejandro Abdelnur commented on YARN-1274:
------------------------------------------

[~sseth], now that you mention the log dirs, while debugging this with [~rvs] he noticed that as well, I've forgot to mentioned here as that does not seem to stop things from working, but we should fix that as well.

> LCE container launch assumes the usercache/USER directory exists and it is owned by the user running the container process.
> But the directory is created only if there are resources to localize by the LCE localization command, if there are not resourcdes to localize, LCE localization never executes and launching fails reporting 255 exit code and the NM logs have something like:
