Subject [jira] [Created] (HDFS-5214) ProxyUsers does not work with NetGroups
Date Mon, 16 Sep 2013 23:58:51 GMT
Benoy Antony created HDFS-5214:

             Summary: ProxyUsers does not work with NetGroups
                 Key: HDFS-5214
                 URL: https://issues.apache.org/jira/browse/HDFS-5214
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Benoy Antony
            Assignee: Benoy Antony

It is possible to use NetGroups for ACLs. This requires specifying  the config property org.apache.hadoop.security.ShellBasedUnixGroupsNetgroupMapping
as  org.apache.hadoop.security.JniBasedUnixGroupsNetgroupMapping or org.apache.hadoop.security.ShellBasedUnixGroupsNetgroupMapping.

The authorization to proxy a user by another user is specified as a list of groups hadoop.proxyuser.<user-name>.groups.
The Group resolution does not work  if we are using NetGroups.
