We already have Quota feature for this. 
Check HBASE-8410.

> 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.
