stack commented on HBASE-1457:
------------------------------

I tested it.  Works great.  There is an issue where if -ROOT- goes down, after 
successful redeploy, I see that the .META. also will be redeployed (says 
assignment is invalid though it is not).  Will make separate issue for this.

Working on the backport.  Its a little sticky.
