wiki and hadoop templates provides wrong superusergroup property instead of
supergroup
--------------------------------------------------------------------------------------
Key: HDFS-3118
URL: https://issues.apache.org/jira/browse/HDFS-3118
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 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
