------------------------------------------
Summary: Remove previous upgrades to allow schema change
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}}.
