> From our experience, cluster can be well balanced and yet, one table's
> regions may be badly concentrated on few region servers.
> For example, one table has 839 regions (380 regions at time of table
> creation) out of which 202 are on one server.
> It would be desirable for load balancer to distribute regions for specified
> tables evenly across the cluster. Each of such tables has number of regions
> many times the cluster size.
