[jira] [Commented] (HBASE-4440) add an option to presplit table to
PerformanceEvaluation
[ https://issues.apache.org/jira/browse/HBASE-4440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13183784#comment-13183784 ]
Jean-Daniel Cryans commented on HBASE-4440:
-------------------------------------------
I tried the patch on 0.92, why is it that using presplit you get a different behavior than while not using it regarding the re-creation of the table? Seems like a bug to me.

> 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)
