Devaraj Das updated HBASE-7213:
-------------------------------

    Attachment: 7213-in-progress.2.2.patch

Addresses most of the comments..

One thing I didn't change is 
bq. The check for ROOT region above is for assigning ROOT ..

In HBASE-3171, there is work underway to remove -ROOT- .. So not much gain here 
to address things to do with how the root region is handled. I have left it as 
such (with a known and a very corner case that if the server holding the root's 
region crashes before the region's edits are persisted, the assignment of the 
region might be an issue).

Manual tests seemed to indicate things are working well. I'll start the full 
set of unit tests now.

> Over on HBASE-6774, there is a discussion on separating out the edits for 
> .META. regions from the other regions' edits w.r.t where the edits are 
> written. This jira is to track an implementation of that.
