Re: Hadoop-on-demand and torque
FWIW: Open MPI now has an initial cut at "MR+" that runs map-reduce under any HPC environment. We don't have the Java integration yet to support the Hadoop MR class, but you can write a mapper/reducer and execute that programming paradigm. We plan to integrate the Hadoop MR class soon.

If you already have that integration, we'd love to help port it over. We already have the MPI support completed, so any mapper/reducer could use it.
