------------------------------------------------

The doc suggests that only the master updates the meta. In the master branch
the HMaster itself is am HRS.
In the OpenRegionHandler we still do updateMeta(). So is that done by the
RegionServer or the master?
{code}
if (!updateMeta(region) || this.server.isStopped() ||
this.rsServices.isStopping()) {
return;
}
{code}

> 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.
