Tsz Wo (Nicholas), SZE commented on HADOOP-4727:
------------------------------------------------

I think the correct semantic is to require that the users and groups in HDFS 
must exist in the local host when using fuse.  So if a user or group is not 
found locally, throw an exception.

BTW, 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?  We probably 
should do the same.

> Groups do not work for fuse-dfs out of the box on 0.19.0
