Deprecate dfs.permissions.superusergroup in favor of
hadoop.cluster.administrators
----------------------------------------------------------------------------------
Key: HDFS-1008
URL: https://issues.apache.org/jira/browse/HDFS-1008
Project: Hadoop HDFS
Issue Type: Bug
Components: security
Reporter: Vinod K V
Fix For: 0.22.0
HADOOP-6568 added the configuration {{hadoop.cluster.administrators}} through
which admins can configure who the superusers/supergroups for the cluster are.
HDFS itself already has {{dfs.permissions.superusergroup}} (which is just a
single group). As agreed upon at HADOOP-6568, this should be deprecated in
favor of {{hadoop.cluster.administrators}}.
