>                 Key: HDFS-3118
>                 URL: https://issues.apache.org/jira/browse/HDFS-3118
>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 1.0.1, 1.0.0
>         Environment: Used Debian package install
>            Reporter: Olivier Sallou
>            Priority: Minor

> The hdfs-site template and the wiki: http://hadoop.apache.org/hdfs/docs/current/hdfs_permissions_guide.html#The+Super-User
> refers to property dfs.permissions.superusergroup to define the group of superuser.
> However we must use the property dfs.permissions.supergroup, and not superusergroup,
to make it work.
> In file src/hdfs/org/apache/hadoop/hdfs/server/namenode/FSNamesystem.java, supergroup
is extracted from:
> this.supergroup = conf.get("dfs.permissions.supergroup", "supergroup");
> It does not make use of DFS_PERMISSIONS_SUPERUSERGROUP_KEY
