Jean-Daniel Cryans commented on HBASE-3373:
-------------------------------------------

Just to clear up some confusion, trunk is going to be 0.94 so what you're playing with is
probably 0.90.4

> 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.
