> HADOOP-6568 added the configuration {{hadoop.cluster.administrators}} through which admins can configure who the superusers/supergroups for the cluster are. MAPREDUCE itself already has {{mapred.permissions.supergroup}} (which is just a single group). As agreed upon at HADOOP-6568, this should be deprecated in favor of {{hadoop.cluster.administrators}}.
