--------------------------------------------
Summary: Ambari Replaces the Value of Undefined Service
Configuration Properties with "Undefined" in Default Config Group If the Same
Property is Defined in Different Config Group
Key: AMBARI-21848
URL: https://issues.apache.org/jira/browse/AMBARI-21848
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.5.1
Reporter: Aleksandr Kovalenko
Assignee: Aleksandr Kovalenko
Priority: Blocker
Fix For: 2.6.0
_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"
