>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.1.0
>            Reporter: Di Li
>            Assignee: Di Li
>             Fix For: 2.1.0

>
> 1. Perform rolling upgrade
> 2. Clicked Downgrade once it reached the "Finalize" step.
> 3. Once the downgrade finished successfully, went to the "Stack and  Versions" page and clicked the Rolling upgrade button.
> 4. The rolling upgrade failed the precheck with error "All hosts should have target version installed"
> The binaries (RPMs) however were installed. 
> This seems to be a issue in the database and the HostsRepositoryVersionCheck.java where the check expects the BI 4.1 repo on each host to be in the "INSTALLED" state, whereas the database still has the state as "UPGRADED" after the downgrade.
> Workaround is to click the "Reinstall Packages" button first, wait for the reinstall to finish (should be very quickly as the RPMs were already installed), then click Rolling Upgrade.
