> PerformanceEvaluation a quick way to 'benchmark' a HBase cluster.  The current 'write*'
operations do not pre-split the table.  Pre splitting the table will really boost the insert
performance.
> It would be nice to have an option to enable pre-splitting table before the inserts begin.
> it would look something like:
> (a) hbase ...PerformanceEvaluation   --presplit=10 <other options>
> (b) hbase ...PerformanceEvaluation   --presplit <other options>
> (b) will try to presplit the table on some default value (say number of region servers)
