+The Spark web interface is here [[http://spark.cs.ndsu.edu:8080/|Spark Master]].
+**Note:** Status and information pages are only available from NDSU CS Department office and lab computers.
+===== Firewall info =====
+The head node is firewalled such that Spark status links are ONLY accessible from /* ND state */ CS Dept networks. The Spark head node can be accessed via SSH from anywhere (**not being blocked from your home country or ISP**), so job submission is possible from outside of these networks, but it is currently not possible to view the status pages for security purposes.
+===== Spark Components =====
+The current version of Spark installed does NOT support HDSF
