Service exposition with ListenerClasses
The Operator deploys a service called <name>-<role>-<rolegroup> (where <name> is the name of the HdfsCluster, <role> is the role and <rolegroup> the name of the role group) through which the different HDFS processes can be accessed. Unlike many other Stackable Operators, the HDFS Operator does not deploy role-level Services.
These services can have either the cluster-internal or external-unstable type. external-stable is not supported for HDFS at the moment. Read more about the types in the service exposition documentation at platform level.
This is how the listener class is configured:
spec:
clusterConfig:
listenerClass: cluster-internal (1)
