Francis Liu commented on HBASE-11059:
-------------------------------------
Interesting, I suspect zk is signifcantly slower because it syncs to disk
(unlike hdfs). Can we have a run without forceSync=no?

For a patch for 0.98, let me give it a try. We need HBASE-10569 too.

Does it require the new deployment to make things work? Or is there just some
bits of code change that it depends on? We will keep the original deployment
supported still correct?

By the way, in the test, I set both openregion/closeregion thread to 20. The
default is 3.

Are there any other configs you changed?

> 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.
