Subject [jira] [Commented] (HBASE-3647) Distinguish read and write request count in region

> The action for balancing read vs. write load should be different. For read load, region
movement should be low (to keep scanner happy). For write load, region movement is allowed.
> Now that we have cheap(er) counters, it should not be too burdensome keeping up the extra
