      Description

      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.
