--------------------------------------------------------------
The patch is backward compatible, rolling upgradable. The performance depends
on the setup and the number of regions of course. On my 6 nodes cluster,
assigning 13,990 user regions, it took about 8minutes using ZK, and ~1minute
with this patch (no ZK).

> It seems that most people don't like region assignment with ZK (HBASE-5487),
> which causes many uncertainties. This jira is to support ZK-less region
> assignment. We need to make sure this patch doesn't break backward
> compatibility/rolling upgrade.
