> 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
