> Key: AMBARI-14734
> URL: https://issues.apache.org/jira/browse/AMBARI-14734
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 2.2.1
>
>
> Customer quit on Save Cluster State and finalized the upgrade later without
> running "ambari-server set-current --cluster-name=$CLUSTERNAME
> --version-display-name=$VERSION_NAME".
> Next upgrade from 2.3.2 to 2.3.4 deleted configs from desired stack 2.2
> STR:
> RU/EU HDP 2.2->2.3 (don't Save Cluster State so that desired stack remains on
> 2.2)
> RU/EU from HDP 2.3.0.0-2.3.4.0 and Downgrade (this will remove the configs
> for the desired stack, which is still 2.2!)
> Need stronger prechecks to prevent starting RU/EU if the previous upgrade did
> not have a downgrade path and the "Save Cluster State" step is not COMPLETED.
