--------------------------------------------
Summary: RU/EU, add PreCheck to prevent starting upgrade if a
previous upgrade skipped the step Save DB State
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.
