Jimmy Xiang commented on HBASE-11059:
-------------------------------------
[~jeffreyz], yes, it needs meta/master colocation. This patch makes sure only
master updates the meta.
[~toffer], I also set hbase.bulk.assignment.waittillallassigned to true since
I'd like to get the assignment time only. I didn't change forceSync. So the
default value should be used. The reason we need HBASE-10569 is that the patch
talks to the meta region directly in persisting region state changes. If meta
is on a different server, the performance shouldn't be the same. The new
deployment is used in my testing. But the original deployment is still
supported, with some performance hurt of course.

> 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.
