+# Environment Variables
+#
+#   SPARK_CONF_DIR  Alternate conf dir. Default is ${SPARK_HOME}/conf.
+#   SPARK_LOG_DIR   Where log files are stored. ${SPARK_HOME}/logs by default.
+#   SPARK_MASTER    host:path where spark code should be rsync'd from
+#   SPARK_PID_DIR   The pid files are stored. /tmp by default.
+#   SPARK_IDENT_STRING   A string representing this instance of spark. $USER by default
+#   SPARK_NICENESS The scheduling priority for daemons. Defaults to 0.
+#   SPARK_NO_DAEMONIZE   If set, will run the proposed command in the foreground. It will not output a PID file.
