Swapan Shridhar resolved AMBARI-22031.
--------------------------------------
Resolution: Not A Problem
> Invalid error message on UI after performing downgrade - Before finalizing
> the upgrade
> --------------------------------------------------------------------------------------
>
> Key: AMBARI-22031
> URL: https://issues.apache.org/jira/browse/AMBARI-22031
> Project: Ambari
> Issue Type: Bug
> Components: ambari-upgrade
> Affects Versions: 2.6.0
> Environment: ambari-server --version 2.6.0.0-128
> Reporter: Supreeth Sharma
> Priority: Critical
> Labels: patch-upgrade
> Fix For: 2.6.0
>
>
> Invalid error message is shown on the UI when user performs downgrade from
> mid point.
> Live cluster : http://172.22.83.55:8080/
> Steps to reproduce :
> 1) Install ambari 2.6.0.0 with HDP-2.6.3.0 (Error could be seen on all the
> HDP versions)
> 2) Start the patch upgrade for Hive or storm. (I guess this issue will occur
> for all the services which asks user to perform manual steps and provides the
> option to do downgrade.)
> 3) In the second step when user is asked to perform manual steps, option is
> available to do downgrade. Click on downgrade.(Attaching the screenshot)
> 4) Downgrade completes successfully. But error message 'Upgrade Action
> Required' is still shown on the UI. (Attaching the screenshot)
> Workaround : Cluster looks good and error message is removed after performing
> ambari-server restart
