> [--targetRegionCount=] [--printExecutionPlan=] [--configMergePauseTime=]
> Options:
> --h or --h print help
> --tableName table name must be not null
> --startRegion start region
> --stopRegion stop region
> --maxRegionSize max region size Unit GB
> --maxRegionCreateTime max Region Create Time yyyy/MM/dd HH:mm:ss
> --numMaxMergePlans num MaxMerge Plans
> --targetRegionCount target Region Count
> --configMergePauseTime config Merge Pause Time In milliseconds
> --printExecutionPlan Value default is true print execution plans false is
> execution merge
