+#
+#   SPARK_WORKER_INSTANCES  The number of worker instances to run on this
+#                           slave.  Default is 1.
+#   SPARK_WORKER_PORT       The base port number for the first worker. If set,
+#                           subsequent workers will increment this number.  If
+#                           unset, Spark will find a valid port number, but
+#                           with no guarantee of a predictable pattern.
+#   SPARK_WORKER_WEBUI_PORT The base port for the web interface of the first
+#                           worker.  Subsequent workers will increment this
+#                           number.  Default is 8081.
