Subject [jira] [Created] (AMBARI-6759) Switching host to config-group with final flag turned off does not reflect in file

Srimanth Gunturi created AMBARI-6759:
----------------------------------------

             Summary: Switching host to config-group with final flag turned off does not reflect
in file
                 Key: AMBARI-6759
                 URL: https://issues.apache.org/jira/browse/AMBARI-6759
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.7.0
            Reporter: Srimanth Gunturi
            Assignee: Srimanth Gunturi
             Fix For: 1.7.0


In the default config-group for HDFS I had a config with final=true. I then created a config-group
with only the final flag turned off (final=false), and same value. When I restarted the service,
I still see the {code}<final>true</final>{code} in the hdfs-site.xml
