["stack (JIRA)" <ji...@apache.org>]

stack commented on HBASE-1816:
------------------------------

I've been adding to http://wiki.apache.org/hadoop/Hbase/MasterRewrite.  Have proposal for moving schema and state out to zk but still a bit stuck on how to do regions.  Regions need to stay in .META. once they've been deployed, I think, because .META. scales better and zk (though patrick and mohadev yesterday claimed 100k small objects should be fine in a dedicated quorum) and because you can't do getClosest against zk -- not yet anyways.
