stack commented on HBASE-3507:
------------------------------
I just committed part 1 of this patch. Thanks Ted and Sebastian for
persisting.
Regards part 2, it looks a bit wonky to me. You are balancing based off
requests though the balancer in place is balancing off the count of regions
(you are running the balance yourself manually, external to hbase). Thats
kinda cool but I'm not sure I should commit it. For example, the name of the
shell command is 'rebalance' when it probably should be
'rebalance_based_off_region_hits_but_native_balancer_must_be_disabled'?
Thanks lads.
