Looks good.
I think the thought is that we do not check in these jruby scripts any more because they have a tendency to rot as APIs change, etc. Attach the script to the issue for folks who need this facility? Or what do you think Liyin?
INLINE COMMENTS
bin/region_balance_checker.rb:46 THis can be null sometimes seemingly so do a getHRegionInfoOrNull instead and check for null when it comes back?
