stack commented on HBASE-1302:
------------------------------

Yes, I did as you speculated J-D.  I changed hbase-site.xml only.  And yes, I 
agree, we need to fix it but it belongs elsewhere.

I took a quick look at patch and looks good.  I'd say go ahead and commit.

> After HBASE-1205, we can now handle a master going down and coming up 
> somewhere else. When this happens, the new master will scan everything and 
> reassign all the regions, which is not ideal. Instead of doing that, we 
> should keep the region assignments from the last master.
