> *Service instance level* configs are the ones that are associated with a *serviceId* while *cluster level* configurations are those which are not. Historically all configs were *cluster level* as there were no service instances. In the future all configs will be service instance level with the temporary exception of _cluster-env_.
> Ambari code uses *Cluster.getConfig(String configType)* method almost everywhere which returns *cluster level* configurations only. Luckily, all configs on *service instance level* are also stored as *cluster level* configs in memory in *ClusterImpl*, this is why it has worked so far.
> Double-storing *service instance level* configs on the *cluster level* will not work once multiple service instances will be enabled as ambiguity would occur.
> The *Cluster.getConfig(String configType)* method should be eliminated and the *Cluster.getConfig(String configType, Optional<Long> serviceId)* method used instead. *serviceId* should be given in all cases except when not applicable (_cluster-env_)
