Ravi Gummadi commented on MAPREDUCE-1542:
-----------------------------------------
Removing mapred.permissions.supergroup and the recently renamed
mapreduce.jobtracker.permissions.supergroup in favour of the config
hadoop.cluster.administrators that can take sequence of users followed by
sequence of groups.
As mapred.permissions.supergroup is not documented anywhere and as maintaining
compatibility between mapred.permissions.supergroup and
hadoop.cluster.administrators seems to be very difficult(would need lot of
hacking in the code as the values for these 2 keys are different and in
different formats), the old config will not be supported with this 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}}.
