> When provisioning a cluster using a blueprint that contains HA components or an existing MYSQL_SERVER or implicit MYSQL_SERVER (not explicitly specified in blueprint but required by dependency) the cluster fails to deploy.
> The request remains in the PENDING state and at 0% complete.
> Output like the following is logged to ambari-server.out:
> {code}
> TopologyManager.ConfigureClusterTask: Entering
> Caught an error from Config Processor: java.lang.IllegalArgumentException: Unable to determine required host groups for component. Component 'MYSQL_SERVER' is not mapped to any host group or is mapped to multiple groups.
> {code}
> This is a regression as a result of  https://issues.apache.org/jira/browse/AMBARI-10750
> The problem was that the blueprint config processor was not dealing with these topologies properly when trying to determine which host groups needed to be resolved prior to updating configuration.
