---------------------------------------

             Summary: hdfs superuser (usually user 'hdfs') should be in group dfs.cluster.administrators
                 Key: AMBARI-9377
                 URL: https://issues.apache.org/jira/browse/AMBARI-9377
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.0.0


Noticed this on a HA cluster where the dfsadmin fetch image call failed with a
403 error.

Fetch image call uses the value in dfs.cluster.administrators (hdfs-site.xml)
to determine who the admin is. That is set to group hdfs. Other dfsadmin calls
as user hdfs who belongs to group hadoop go through. But fetch image does not
as hdfs does not belong to group hadoop. We should either add hdfs user to
group hdfs or change this property to be set to group hadoop.
