> As reported by [~gbaecher] up on the mailing list, there is a regression in
> 1.2. The regression is in a CDH version of 1.2 actually but the CDH hbase is
> a near pure 1.2. This is a working issue to figure which of the below changes
> brought on slower writes (The list comes from doing the following...git log
> --oneline
> remotes/origin/cdh5-1.2.0_5.8.0_dev..remotes/origin/cdh5-1.2.0_5.9.0_dev ...
> I stripped the few CDH specific changes, packaging and tagging only, and then
> made two groupings; candidates and the unlikelies):
