> Key: HBASE-24633
> URL: https://issues.apache.org/jira/browse/HBASE-24633
> Project: HBase
> Issue Type: Improvement
> Components: Balancer
> Affects Versions: 2.3.0
> Reporter: Huaxiang Sun
> Assignee: Clara Xiong
> Priority: Major
>
> We found one of the clusters with read replica enabled always balance lots of
> replica regions. going through the balancer's cost functions, found that data
> locality and StoreFileCost have same multiplier for both primary and replica
> regions. That is something we can improve. Data locality for replica regions
> should not be a dominant factor for balancer. We can either remove it out of
> balancer's picture for now and give it a small multiplier.
