-Hadoop 2.8.5 is installed in the CS Dept. Lab in the folder: /usr/lib/hadoop. You'll find the Hadoop binaries and scripts at /usr/lib/hadoop/bin.
+Hadoop 2.10.2 is installed in the CS Dept. Lab in the folder: /usr/lib/hadoop. You'll find the Hadoop binaries and scripts at /usr/lib/hadoop/bin.
 If you are a member of the 'hadoop' group, you will be able to access hadoop to submit new jobs.

 Hadoop makes use of the HDFS (Hadoop Distributed File System). Hadoop node computers are configured to be a node in an HDFS cluster. There's a bit of space here (about 14TB) so don't feel shy about using it, but please delete your large data files when they are no longer needed.
+Credentials for the Hadoop cluster are your NDSU credentials.
 To become a member of the 'hadoop' group, email <labsupport@cs.ndsu.edu>. You will be added to the group and a folder in the HDFS filesystem will be made for you.

 ===== Firewall info =====
-The head node is firewalled such that Hadoop is ONLY accessible from ND state networks. It can be accessed via SSH from anywhere, so job submission is possible from outside of these networks, but it is currently not possible to view the status pages.
