>
> Coordinators subscribe to 3 statestore topics: catalog-update,
> impala-membership and impala-request-queue. The last two topics are about
> query scheduling. To separate the cluster or share catalogd and statestore
> across Impala clusters, we can add the cluster id to these two topic names.
> Impalads are only visible to each other inside the same cluster (i.e. using
> the same cluster id). Queries won't be scheduled across clusters.
> h4.
