> Key: HBASE-26618
> URL: https://issues.apache.org/jira/browse/HBASE-26618
> Project: HBase
> Issue Type: Improvement
> Components: meta replicas
> Affects Versions: 2.4.9
> Reporter: Huaxiang Sun
> Assignee: Huaxiang Sun
> Priority: Minor
>
> In the current release with Meta replica LoadBalance mode, the primary meta
> region is not serving the meta scan (only meta replica region serves the
> read). When the result from meta replica region is stale, it will go to
> primary meta region for up-to-date location.
> From our experience, the primary meta region serves very less read traffic,
> so it will be better to load balance read traffic across the primary meta
> region as well.
