> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 2.5.1
> Reporter: Aleksandr Kovalenko

> _PROBLEM:_
> If Custom *-site properties are added to a non-default config group in Ambari
> 2.5.0 or 2.5.1, these same properties will be set to "Undefined" in the
> default config group when a different default configuration group property
> for the same service is modified.
> _BUSINESS IMPACT:_
> This can result in services failing to restart for certain properties (e.g.
> hive.server2.thrift.bind.host)
> _STEPS TO REPRODUCE:_
> 1. Install Ambari-2.5
> 2. Create config group for any service.
> 3. Add override for this new group in some custom *-site.
> 4. Make change in default config group for the same service.
> _EXPECTED RESULT:_
> Property overriden in step 3 will not exist in default config group
> _ACTUAL RESULT:_
> Property overriden in step 3 has value "Undefined"
