With the augmented instructions that follow. These are the steps your students most likely will follow as well. Stay tuned for official instructions. Let me know if you do not get an account set up and

To start a hadoop session with a persistent hdfs requires three simple
steps:
# 1. start an interactive job with at least 3 nodes
interact -N 3
# 2. load the hadoop module when the job starts
module load hadoop
# IMPORTANT: do NOT run start-hadoop.sh as the module suggests.
# 3. instead, run this:
/opt/packages/hadoop-testing/persist-start.sh
# end commands
