>          Components: ambari-server
>    Affects Versions: 2.2.0

> If a cluster has version x (e.g., HDP 2.3.2.0-2950) as CURRENT, and the user registers a Repository Version such as 2.3.xx that uses different build URLs but results in the same build number, then installing packages will be a no-op.
> This means that no new version will be detected using the "deltas" method and the repo_version entity will keep the "version" field without a build number, and the Cluster Version entity will transition into INSTALLED (since technically it is already installed).
> This incorrect setup will allow the user to start a RU/EU, which will immediately fail since the Repo Version has no build number, which is needed by hdp-select. 
> The fix is to add a PreCheck that ensures that all repos contain a build number.
