> Key: AMBARI-15569
> URL: https://issues.apache.org/jira/browse/AMBARI-15569
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 2.2.2
>
> Attachments: AMBARI-15569.trunk.patch

>
> *STR:*
> # Install Ambari 2.2.0
> # Upgrade stack from HDP-2.2.4 to HDP-2.3.2
> # At finalize step, choose downgrade option
> # Introduce failures in some clients such as Zookeeper and Yarn.
> In this case, the status of some tasks are marked as ABORTED.
> This causes the overall status of the Downgrade to be ABORTED, and hence the
> UI shows an incorrect message and button.
> Technically, the Downgrade is still progressing, yet the UI shows "Downgrade
> paused" and a button to "Resume Downgrade"
> This means that the calculations of the stages is incorrect.
