-------------------------------------
No problem. Please just look v3. During to rebasing, v1->v3 diff may pull
something else in.
bq. Do you think we could finish that transition in like 1.1 or it would have
to wait till 2.0?
Probably not. As you said, we can't enforce people to migrate off ZK during
rolling upgrade, at least inside the same major version. It's up to the
community. I think it's fair to move off ZK (assignment) completely in 2.0
instead of 1.1

> 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.
