Bugs: AMBARI-19464
    https://issues.apache.org/jira/browse/AMBARI-19464


Repository: ambari


Description
-------

AMBARI-18335 addresses an issue where configuration properties in the Kerberos 
descriptor don't change during a stack upgrade. It accounts for both 
upgrade/downgrade scenarios and situations where properties are added/removed.
However, it does not take into account the potential for a property to be 
customized by the user (not a new property, but a property which the user 
changes the value of). In this case, the downgrade would be destructive, 
overriding the user's values with those from the downgrade stack.
