Subject [jira] [Created] (HBASE-4440) add an option to presplit table to PerformanceEvaluation

add an option to presplit table to PerformanceEvaluation

                 Key: HBASE-4440
                 URL: https://issues.apache.org/jira/browse/HBASE-4440
             Project: HBase
          Issue Type: Improvement
          Components: performance
            Reporter: Sujee Maniyam
            Priority: Minor

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)
