correctly
Resolution: Resolved
> HDFS user permission does not work correctly
> --------------------------------------------
>
> Key: HDFS-15615
> URL: https://issues.apache.org/jira/browse/HDFS-15615
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Heba Aboulmagd
> Priority: Major
>
> HDFS users can create/delete folders for each other, while the permission is
> set to {{745}} on {{/user/username}}.
> I used the following commands to create users and set their permissions
> {{useradd -m -g hdfs username}}
> {{su hdfs}}
> {{hdfs dfs -mkdir -p /user/username}}
> {{hdfs dfs -chown username:hdfs /user/username}}
> {{hdfs dfs -chmod 745 /user/username}}
> when {{user1}} executes: {{hdfs dfs -mkdir /user/user2/from_user1}}
> {{The directory is created successfully}}
> The same happens when {{user1}} tries to delete files from {{/user/user2}}
> while the permission is set to read only for the users in the same group.g
