I'm a Hadoop and related software sysadmin at the University of Michigan. I'm a student still, so it's only a part-time position. I have some documentation at http://caen.github.io/hadoop - if something is not clear, I will gladly take feedback and make appropriate changes.

I'll try to chime in on any questions about scheduling/clusters in the future as we have a pretty large installation (~20,000 cores) running a traditional HPC stack, and a small Hadoop cluster. > [2] http://hadoop.apache.org/docs/r1.2.1/cluster_setup.html Hadoop is currently "stable" on 2.x (specifically 2.4), so relevant documentation is at http://hadoop.apache.org/docs/stable.
