> 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.
