Ted Yu updated HBASE-3373:
--------------------------
Description:
>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.
