>
> Building the hostComponentMap map for ProviderModule seems does unnecessary
> computation going through the ResourceProvider layer. On every configuration
> update, we call the reset on these maps which takes a long time to refresh.
> Instead, relying on
> org.apache.ambari.server.state.cluster.ClusterImpl#serviceComponentHosts will
> lead to faster computation without overhead like stale config calculations
> for every SCH.
