-----------------------------------
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.
