Subject [jira] Updated: (HDFS-685) Use the user-to-groups mapping service in the NameNode
Date Fri, 18 Dec 2009 01:00:23 GMT

     [ https://issues.apache.org/jira/browse/HDFS-685?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jakob Homan updated HDFS-685:

    Hadoop Flags: [Reviewed]

+1 pending Hudson for v6 of patch.  We can use Mockito for some of the explicit extension
of classes for mocking purposes, but I believe this code is going to churn a lot with the
new UGI stuff that's coming, so I'm not concerned about using it now.

by the client.
