>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.4.0
>            Reporter: Jonathan Hurley
>            Assignee: Jonathan Hurley
>            Priority: Blocker
>             Fix For: 2.4.0

> STR:
> - Install Ambari 2.2.2 with Hive on HDP 2.4.2.0 and Kerberize
> - Upgrade to Ambari 2.4.0
> - Upgrade to HDP 2.5
> - Distribute Keytabs
> - Add a new service
> At this point, the UI flags Hive as having configurations which need attention. The follow are all blank and are marked as required:
> {code}
> hive-site/hive.server2.authentication.ldap.url
> hiveserver2-site/hive.conf.restricted.list
> hiveserver2-site/hive.security.authenticator.manager
> hiveserver2-site/hive.security.authorization.manager
> {code}
> There are actually two problems here:
> - The Kerberos wizard interprets the stack advisor "delete" attribute and improperly sets config properties to blank instead of actually removing them
> - The upgrade logic is adding properties back when it should not.
> The Kerberos issue aside, we can't be adding properties back during upgrade stack merging when those properties were specifically removed by the stack advisor prior.
> For example (Ambari 2.2.2 installed with HDP 2.x)
> - Ambari 2.2.2 does not have {{foo-site/property}} for HDP 2.x
> - Ambari 2.4.0 adds {{foo-site/property}} for HDP 2.x, but instructs the upgrade not to add it
> - An upgrade to HDP 2.y sees that {{foo-site/property}} doesn't exist and thinks it's brand new and needs to be merged.
> The upgrade logic should check to see if {{foo-site/property}} is part of both 2.x and 2.y default configurations. If it's part of both of them and is not currently set, then upgrade should NOT set it.
