Tom White commented on YARN-253:
--------------------------------
Thanks Vinod. Looking at LCE, it seems to handle this case already since
create_container_directories uses mkdirs which will create parent directories
as needed.
I'll create another patch which removes the comment and temp files.
> Container launch may fail if no files were localized

> This can be demonstrated with DistributedShell. The containers running the
> shell do not have any files to localize (if there is no shell script to copy)
> so if they run on a different NM to the AM (which does localize files), then
> they will fail since the appcache directory does not exist.
