> 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
> Assignee: Hairong Kuang
> Priority: Blocker
> 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"
