> The current namenode benchmark (org.apache.hadoop.examples.NNBench) uses
> map/reduce to distribute a load on the namenode. For the purposes of loading
> the namenode, this model gives insufficient control over job start and
> failure recovery. I propose the namenode benchmark be re-written to use
> slaves.sh directly to execute the namenode benchmark. The benchmark should
> also give finer control over the operations executed and the timings reported.
