Brandon Li commented on HDFS-6689:
----------------------------------
This is due to a bug in Nfs3Utils#getAccessRights(), which doesn't give
execution permission to directories.

> 2. Upload a file at /user/userX/TestFile with 644 as userX
> 3. Try to access WriteTest as userY.
> HDFS will allow to read TestFile.

> uid=661(userY) gid=100(users) groups=100(users),13016(groupY)
> bash-4.1$ hdfs dfs -cat /user/userX/TestFile
> create a file with some content
> {noformat}
> NFS will not allow to read TestFile.
