> Project: Ambari
> Issue Type: Task
> Components: ambari-server

> Currently there is an odd scenario which can occur when patch repositories
> are registered which have services not yet installed. Consider the following
> scenario:
> - Install ZooKeeper, Storm on HDP 2.6.0.0-1234
> - Register/patch a {{PATCH}} VDF for Storm and Accumulo for 2.6.0.1-9999
> - Install Accumulo
> Which version does Accumulo use - the {{STANDARD}} repository or the
> {{PATCH}}? If the {{PATCH}} repository is chosen, this will now prevent
> reversion of the patch since there's no prior version for Accumulo to revert
> back to.
> If Accumulo uses the {{STANDARD}} repo, then there needs to be a lot of
> design and UX flow work provided to indicate that a {{PATCH}} which was
> previously applied can be re-applied for the new service. This also causes
> problems for patch reversion since now there would be two upgrades which need
> to be reverted to "get rid" of the patch.
> For the timeframe for Ambari 2.6, we should reject VDFs that include services
> which are not installed. This will prevent the problem.
