             Summary: Ambari drops core-site.xml parameters when adding Tez service
                 Key: AMBARI-6656
                 URL: https://issues.apache.org/jira/browse/AMBARI-6656
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 1.6.0
            Reporter: Rémy SAISSY
         Attachments: hbase-error.txt, oozie-error.txt

Hi,
we upgraded a secure cluster from an HDP 2.0.6 stack (Ambari 1.4.4 and Hadoop 2.2) to an HDP 2.1.3 stack (Ambari 1.6.0 and Hadoop 2.4).

Once completed the upgrade, we added the Tez service through Ambari.

After the operation, the core-site.xml configuration in Ambari has been wiped 
out and replaced by these two entries:

hadoop.proxyuser.falcon.groups: *
hadoop.proxyuser.falcon.hosts: *

The Falcon service has not been installed on this cluster.

Another related issue is that after adding the Tez service, Ambari asks for restarting many services.
Doing that lead to errors due to missing entries in the config dictionary for Oozie (oozie_keytab) and HBase RegionServer (hbase_user_keytab).


Everything worked fine before adding the service.
