---------------------------------------------
You clearly don't want to know my thoughts, given the conversation that
happened in this very jira months ago.
> Deprecate mapred.permissions.supergroup in favor of
> hadoop.cluster.administrators

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: security
> Reporter: Vinod K V
> Assignee: Ravi Gummadi
> Fix For: 0.22.0
>
> Attachments: 1542.20S.1.patch, 1542.20S.patch, 1542.patch,

> 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}}.
