Jean-Marc Spaggiari updated HBASE-8803:
---------------------------------------
Status: Patch Available (was: Reopened)
Here we go.
Updated version:
- Added maxthreads parameter to region_mover.rb and graceful_stop.sh.
- If maxthreads is < RS then go random, else go roundrobin.
Tested on 0.94, don't have a way to test it on trunk :(
> region_mover.rb should move multiple regions at a time
