> When creating a cluster using Blueprints that has configuration properties
> defined at host group level Ambari should create a config group for those
> configuration properties when the first host is assigned to the host group.
> In case the host group expects multiple host the config group creation fails
> with the error below if among those host there are hosts which were not
> assigned to the cluster yet.
