Subject [jira] Updated: (MAPREDUCE-1542) Deprecate mapred.permissions.supergroup in favor of hadoop.cluster.administrators
Date Mon, 15 Mar 2010 05:59:27 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1542?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravi Gummadi updated MAPREDUCE-1542:
------------------------------------

    Attachment: 1542.20S.1.patch

> So, why can't the mrowner and acls be created inside this class when it is instantiated
? Then, isMROwnerOrAdmin can be implemented directly in JobACLsManager itself.

Moved adminsACL and the method isMROwnerOrAdmin() to JobACLsManager. Since mrOwner is used
in JobTracker and TaskTracker at few other places, keeping mrOwner as part of JobTracker and
TaskTracker objects instead of moving to JobACLsManager.

Attaching patch for earlier version of hadoop with review comments incorporated. Not for commit
here.

> 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}}.
