WangYuan created HBASE-17983:
--------------------------------

             Summary: control region numbers when create table to improve performance
                 Key: HBASE-17983
                 URL: https://issues.apache.org/jira/browse/HBASE-17983
             Project: HBase
          Issue Type: Improvement
          Components: Admin, Client
    Affects Versions: 2.0.0
            Reporter: WangYuan
            Priority: Minor
             Fix For: 2.0.0


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.
