Jonathan Hsieh updated HBASE-6283:
----------------------------------

    Attachment: region_mover.rb

Patch for trunk.  Was originally developed and tested against 0.90 (should apply to all active branches).

Manually tested by having TestLoadAndVerify running and executing region_mover.rb unloads while running.

> 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.
