Hadoop version 2 expands Hadoop beyond MapReduce and opens the door to MPI applications operating on large parallel data stores.
... non-MapReduce algorithms has long been a goal of the Hadoop developers. Indeed, YARN now offers new processing frameworks, including MPI, as part of the Hadoop infrastructure.
