> I thought we had an issue to do this but I can't find it so here is a new one.
> Currently, in master branch, HMaster is a RegionServer and carries meta 
> regions such as hbase:meta. Disable this facility by default until better 
> thought through (I think we should undo master ever carrying regions; FBers 
> are thinking we should go forward with notion that master carries meta/system 
> regions. TODO). I want to disable it because this facility is not finished 
> and meantime I want to test new stuff coming in on master branch w/o this new 
> feature getting in the way.
> Parking here a patch that has how to disable master carrying regions and a 
> probably redundant test that ensures all works when master is not carrying 
> meta regions (added because it WASN'T working for me -- but was pilot error).
