Subject [jira] Updated: (MAPREDUCE-1542) Deprecate mapred.permissions.supergroup in favor of hadoop.cluster.administrators
Date Fri, 12 Mar 2010 08:51:27 GMT

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

Hemanth Yamijala updated MAPREDUCE-1542:
----------------------------------------

    Attachment: mapreduce-1542-y20s.patch

The patch Ravi attached earlier on had changes for HDFS also. After discussing with him, Vinod
and Devaraj, we feel that the changes in HDFS are not required at the moment and do not form
the scope of this JIRA. I am attaching a new patch that removes those changes. I will be reviewing
this. The patch is still not meant 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}}.
