--------------------------------------------
Summary: EU/RU can fail if register a repo without a build number
that already exists, add PreCheck
Key: AMBARI-14281
URL: https://issues.apache.org/jira/browse/AMBARI-14281
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 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.
