Francis Liu you mean 'with', not 'without' in above? You want to see what happens if zk is not sync'ing log?

[~stack] sorry typo, yes compare when zk is not sync'ing. Would be good to also have a separate zkwatcher for assignment.

> 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.
