      Description

      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.

      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
      

      NFS will not allow to read TestFile.

      bash-4.1$ cat /tmp/tmp_mnt/user/userX/TestFile
      cat: /tmp/tmp_mnt/user/userX/TestFile: Permission denied
