Description

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)
