Siddharth Seth commented on YARN-1274:
--------------------------------------

I'm in favour of chanigng the LCE as well. it looks like the log dirs may need to be created
with the correct permissions 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:
> {code}
