> 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.
