> NFS does not allow other user to access a file with 644 permission and a parent with
711 access right.
> Steps to reproduce:
> 1. Create a directory /user/userX with 711 permissions
> 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. 
> {noformat}
> bash-4.1$ id
> 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.
> {noformat}
> bash-4.1$ cat /tmp/tmp_mnt/user/userX/TestFile
> cat: /tmp/tmp_mnt/user/userX/TestFile: Permission denied
> {noformat}
