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

             Summary: OzoneConfiguration is not set in UserGroupInformation while creating
OzoneClient
                 Key: HDDS-2062
                 URL: https://issues.apache.org/jira/browse/HDDS-2062
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Nanda kumar


{{OzoneConfiguration}} is not set in {{UserGroupInformation}} while creating {{OzoneClient}}.
Because of this, programmatically updated configuration values are not reflected inside {{UserGroupInformation}}.

Setting {{hadoop.security.authentication}} via java code is not getting reflected, and the
following error is seen
{noformat}
Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):

It started working once {{hadoop.security.authentication}}  is added to {{core-site.xml}}
