Jimmy Xiang commented on HBASE-11059:
-------------------------------------
bq. I see so it will still work with meta remotely access. IMHO I don't think
the perf degradation will be significant, though would be good to quantify.
The issue is that it is not optimized in this case since I assume meta is
co-located on master. Currently, only one meta HTable instance is used in this
case in a synchronized way. It is better to use a pool of meta HTable
instances.

> 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.
