Jean-Marc Spaggiari commented on HBASE-8803:
--------------------------------------------
So the unload is working as expected. For the unload, that's weird. Maybe it's
"simply" very slow because network is overwhelmed by all hose move? Are you
running on real servers? Or on VMs?
> region_mover.rb should move multiple regions at a time
