In this mode, Spark master will reverse proxy the worker and application UIs to enable access without requiring direct access to their UIs. Use it with caution, as worker and application UI will not be accessible directly, you will only be able to access it through spark master/proxy public URL. This setting affects all the workers and application UIs running in the cluster and must be set on all the workers, drivers and master. --- End diff -- everywhere: "UIs" (since you're saying "worker an application") "...without requiring direct access to their hosts."
