Subject [jira] Commented: (MAPREDUCE-1542) Deprecate mapred.permissions.supergroup in favor of hadoop.cluster.administrators
Date Wed, 10 Mar 2010 06:47:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12843458#action_12843458

Ravi Gummadi commented on MAPREDUCE-1542:
-----------------------------------------

Configuration without default resources does not load *site.xml files also. So needs to change
the logic in buildAdminsACL().

> 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}}.
