develop mechanism to access HDFS over Lustre/networkfs w/o launching a job

I believe through a series of scripting tricks, it would be doable to script this. Hypothetically, launch X hdfs daemons as processes and launch a namenode process on the same node. Configure them to use appropriate paths in lustre/networkfs as their "local drive". Make sure each have separate ports so they communicate to each other on the same node.

No files, tests, or entry points are named. Start by surveying Magpie's Hadoop and filesystem-related scripts, then determine the required process, port, and Lustre/networkfs configuration; done would mean a documented mechanism that accesses HDFS without launching a job.
