> I found that with the increasing number of regions in every RegionServer ,
> HBase read and write performance decreased, and failed to achieve the desired
> performance. Therefore, we hope to control the number of regions in every
> RegionServer , and add the judgment before creating tables.
> I can set up a region parameter in hbase-default.xml,
> hbase.client.region.averageload.numbers, when the client builds a table that
> exceeds the value of this parameter, throws an exception.
