> MPI is commonly used for many machine-learning applications. OpenMPI (http://www.open-mpi.org/) is a popular BSD-licensed version of MPI. In the past, running MPI application on a Hadoop cluster was achieved using Hadoop Streaming (http://videolectures.net/nipsworkshops2010_ye_gbd/), but it was kludgy. After the resource-manager separation from JobTracker in Hadoop, we have all the tools needed to make MPI a first-class citizen on a Hadoop cluster. I am currently working on the patch to make MPI an application-master. Initial version of this patch will be available soon (hopefully before September 10.) This jira will track the development of Hamster: The application master for MPI.
