      Description

      Consider the following two scenarios
      1) With permissions ON, start cluster as user A, create a file as user A, chmod 770 file as user A, access file as user B(using 'get' command)
      The expected behavior would be that user B should be able to access the file since user A and user B are in the same group. But this is not happening. Instead the following error message is displayed "get: Permission denied"

      2) With permissions ON, start cluster as user A, create a file as user A, chmod 700 file as user A, shut down dfs and turn permissions OFF and start up dfs, access file as user B(using 'get')
      The expected behavior would be that user B should be able to access the file since permissions is turned OFF. But this is not happening. Instead the following error message is displayed "get: Permission denied"
