> To enable Ambari server in giving recommendations, we need to provide a
> _/recommendations_ endpoint inside the stack-version URL. Callers will then
> be able to ask a stack-version for its recommendations on host-layout and
> configurations.
> In this JIRA, we will provide configurations recommendation where the
> host-layout has already been determined. Callers will provide the selected
> host-layout, and API will respond with recommended configurations inside the
> provided Blueprint objects.
