> Balancer needs to find the balance of keeping cluster balanced and stable.
> There is a configuration minCostNeedBalance as the threshold of imbalance to
> try to balance. Since we use a single score to combine all the factors we
> consider, it is hard for operation to understand why balancer is "stuck". We
> should add to master-status UI to show balancer is skipping runs and explain
> all factors considered, such as the weight and cost of all cost functions.
