> Allow regions to be load-balanced by table

> Key: HBASE-3373
> URL: https://issues.apache.org/jira/browse/HBASE-3373
> Project: HBase
> Issue Type: Improvement
> Components: master
> Affects Versions: 0.20.6
> Reporter: Ted Yu
> Fix For: 0.94.0
>
> Attachments: 3373.txt, HbaseBalancerTest2.java

>
> 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.
