In the Hadoop-On-Demand world, this is a term used to refer to an HDFS
or a Map/Reduce cluster that's been started outside the HOD provisioning
system. These are also referred to as static clusters, as opposed to the
clusters dynamically allocated by HOD. AFAIK, the terminology is not
native to Hadoop itself.
