> The old NN Bench did not use Map Reduce.
> It was replaced by a new NN Bench that uses Map reduce.
> The old NN Bench is useful and should be restored.
>   - useful ofr simulated data niodes which do not work for Map reduce since the job configs
need to be persistent.
>   - a NN test that is independent of map reduce can be useful as it is one less variable
in figuring out bottlenecks.
