Jonathan Hsieh commented on HBASE-6283:
---------------------------------------
@Stack I'll look into making it throw an exn or at least print a nice warning
message.
Thanks for the pointer to Aravind's work -- this is the first I've seen the
blog. Have we encouraged Aravind to contribute his work?
> [region_mover.rb] Add option to exclude list of hosts on unload instead of
> just assuming the source node.

> 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.
