 = Service exposition with ListenerClasses
+:description: Configure HBase service exposure using ListenerClasses to control internal and external access for all roles.
 
-Apache HBase offers an API.
-The operator deploys a service called `<name>` (where `<name>` is the name of the HbaseCluster) through which HBase can be reached.
-
-This service can have either the `cluster-internal` or `external-unstable` type.
-`external-stable` is not supported for HBase at the moment.
-Read more about the types in the xref:concepts:service-exposition.adoc[service exposition] documentation at platform level.
-
-This is how the listener class is configured:
+The operator deploys a xref:listener-operator:listener.adoc[Listener] for each Master, Regionserver and Restserver pod.
+They all default to only being accessible from within the Kubernetes cluster, but this can be changed by setting `.spec.{masters,regionServers,restServers}.config.listenerClass`:

+<1> Specify one of `external-stable`, `external-unstable`, `cluster-internal` (the default setting is `cluster-internal`).
