[jira] [Created] (AMBARI-24370) Config Group - unable to remove config setting

Hari Sekhon created AMBARI-24370:
------------------------------------

             Summary: Config Group - unable to remove config setting
                 Key: AMBARI-24370
                 URL: https://issues.apache.org/jira/browse/AMBARI-24370
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.5.2
            Reporter: Hari Sekhon


Config Group overrides are unable to remove a setting from being set at all in existing default config.

For example, setting bucket cache on HBase default config group will break HMasters so if you put the HMasters in a separate config group you are unable to remove the settings (setting to zero or none still breaks HMasters, you need to completely unset the config from existing).

Instead you have to move all the RegionServers to another config group, leave the default config group without the setting and then set the config only as an override such that it doesn't exist in default group that HMasters use.
