> Currently, the region_mover.rb script excludes a single host, the host 
> offloading data, as a region move target.  This essentially limits the number 
> of machines that can be shutdown at a time to one.  For larger clusters, it 
> is manageable to have several nodes down at a time and desirable to get this 
> process done more quickly.
> The proposed patch adds an exclude file option, that allows multiple hosts to 
> be excluded as targets.
