> The command generators in Ambari are sending down the {{KeyName.CURRENT_VERSION}} ({{current_version}}) property in the JSON to the agents. This is being used to determine the "current cluster version" which doesn't really exist anymore:
> {code:title=stack_features.py}
>   # something like 2.4.0.0-1234
>   # (or None if this is a cluster install and it hasn't been calculated yet)
>   current_cluster_version = default("/hostLevelParams/current_version", None)
> {code}
> This really needs to be calculated from the service's repository version instead.
