Subject [jira] Commented: (MAPREDUCE-1754) Replace mapred.persmissions.supergroup with an acl : mapreduce.cluster.administrators
Date Mon, 27 Sep 2010 08:19:33 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12915233#action_12915233

Vinod K V commented on MAPREDUCE-1754:

Looked at the patch. Mostly looks good.
 - It is still possible to provide backwards compatibility for {{mapreduce.cluster.permissions.supergroup}}
by simply adding the deprecated group to the new ACL list. If we do this, we should rollback
the changes to ConfigUtil.java and also add one simple test.
 - TestNodeRefresh: For the change in testMRRefreshDefault(), the comment should read as //
refresh by invalid user.
