> 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"
