Duo Zhang commented on HBASE-23297:
-----------------------------------
[~anoop.hbase] I do not think this is the same thing. In the original LB, per
cluster and per table will lead to different result, but here, I think it is
just an optimization to make the balancer faster, so it is an improvement, not
a new feature. Am I correct [~javaman_chen]? Thanks.
> [RSGROUP] build RegionPlan per group not per table

> RSGroupAdminServer#balanceRSGroup will take too long time, if the target
> group has thousands of tables, because we will build RegionPlan for each
> table, I think it’s better to balance per group instead of per table.
