Craig Macdonald commented on HADOOP-4727:
-----------------------------------------
bq. what Linux does if a remote directory is mounted to a local machine but
some accounts used in the remote directory does not exist locally?
Linux reports the uid and gid of the files instead of the username and group
name. However, this isnt an option in this scenario, as we the usernames not
uids are used by Hadoop.
I prefer that the code returns nobody if the user is not known.
