             Summary: Involving primary meta region in meta scan with Meta Replica Mode
                 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


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.
