> Without a "current cluster version", the value being passed into python is
> currently {{None}}. This will be changed as we begin passing down service
> repository versions instead.
> However, in the meantime, there are upgrade failures when this value is empty
> since the fallback code is trying to use "HDP-2.5" and is not able to
> normalize this out to "2.5.0.0":
> {code}
