The documentation: https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.4/html/getting_started_with_jboss_eap_for_openshift_container_platform/reference_information#configuring_kube_ping

Say that not setting the KUBERNETES_NAMESPACE creates a cluster of one. That is not true, It creates a cluster with pods located in the namespace named "default".

 
We already document that KUBERNETES_NAMESPACE must be set. I think that we should update the documentation and remove what happens if not set.
