> map-reduce job overhead is too high. Running a null map-reduce job, with no input, no
intermediate data and no output, on a several-hundred node cluster, takes several minutes,
rather than several seconds.
> Enhanced distribution, launching and monitoring mechanisms should reduce the overhead
to levels that match human online patience for short jobs.
