Subject [jira] Created: (HADOOP-4299) Unable to access a file by a different user in the same group when permissions is set to 770 or when permissions is turned OFF

Unable to access a file by a different user in the same group when permissions is set to 770
or when permissions is turned OFF
------------------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-4299
                 URL: https://issues.apache.org/jira/browse/HADOOP-4299
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.19.0
            Reporter: Ramya R
            Priority: Minor
             Fix For: 0.19.0


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"
