> Key: AMBARI-21397
> URL: https://issues.apache.org/jira/browse/AMBARI-21397
> Project: Ambari
> Issue Type: Task
> Components: ambari-server
> Affects Versions: 2.5.2
> Reporter: Doroszlai, Attila
> Assignee: Doroszlai, Attila
> Priority: Blocker
> Fix For: 2.5.2

>
> AMBARI-21358 introduced schema change to allow tracking upgrade between
> repository versions instead of free text "version" descriptors. Ambari
> Server upgrade currently fails because of this schema change if there are any
> previous upgrades. It's not worth trying to fix the data, and the
> repositories required for the foreign keys may not even be there anymore. So
> we should remove {{upgrade}}, all child data ({{upgrade_group}},
> {{upgrade_item}}, {{servicecomponent_history}}), and the reference from
> {{clusters}}.
