  description: |
    Defines a Spark cluster with a single master in standalone mode,
    and a Zeppelin web notebook front-end. After deploying the
    cluster, the Spark WebUI can be accessed by starting:

      kubectl proxy --port=8001 &

    Then visiting:

      http://localhost:8001/api/v1/proxy/namespaces/default/services/spark-webui/

    The Zeppelin WebUI can be access by finding the Zeppelin pod and port-forwarding:

      kubectl port-forward zeppelin-controller-abcef :8080

    Then visit the forwarded port.
