Research direction

Start by locating the existing Hadoop/HDFS and Lustre integration scripts described by the repository, then trace how a filesystem is selected and configured. Determine the design needed to use Lustre-backed and SSD-backed HDFS filesystems concurrently; done means both storage roles work at the same time without breaking current workflows.
