-----------------------------------
[~claraxiong] Please open a PR for branch-2? The patch for master can not be
applied to branch-2 cleanly, mainly because of UTs...
Thanks.

> URL: https://issues.apache.org/jira/browse/HBASE-26337
> Project: HBase
> Issue Type: Improvement
> Components: Balancer
> Reporter: Clara Xiong
> Assignee: Clara Xiong
> Priority: Major
>
> Currently we use four move candidate generators and pick one randomly for
> every move with even probability, all with optimization associated with a
> certain group of cost functions. We can assign weight for the random picking
> of generators based on balancing pressure on each group.
