------------------------------------
Summary: Stack Downgrade capability
Key: AMBARI-11097
URL: https://issues.apache.org/jira/browse/AMBARI-11097
Project: Ambari
Issue Type: New Feature
Components: ambari-server, ambari-web, stacks
Affects Versions: 2.0.0
Environment: HDP 2.2
Reporter: Hari Sekhon
Priority: Critical
Feature Request to add arbitrary Downgrade capability to any stack. This is
useful if you've upgraded and finalized only to find an issue a few weeks later
that you were sure didn't affect the last version and would like to do a
wholesale Downgrade to test.
Currently after finalizing an upgrade of an Ambari Stack, the ability to deploy
any previous Stack version disappears on the page /#/main/admin/stack/versions
and going to /views/ADMIN_VIEW/2.0.0/INSTANCE/#/stackVersions and doing
"Install On" on a previous stack version does nothing, it returns to the
previous page but the previous stack is not displayed at all, only the current
latest stack is displayed.
