> In 2.1, scaling a UI provisioned cluster via the blueprint add hosts api isn't supported. Support for this use case has been deferred to 2.1.1.
> Currently, if a user attempts to do this, a 500 response is returned.
> This Jira is to fix the error to return a 400 response with a good error message.
