Huaxiang Sun resolved HBASE-26618. ---------------------------------- Fix Version/s: 2.5.0 3.0.0-alpha-3 2.4.12 Release Note: When META replica LoadBalance mode is enabled at client-side, clients will try to read from one META region first. If META location is from any non-primary META regions, in case of errors, it will fall back to the primary META region. Resolution: Fixed > Involving primary meta region in meta scan with > CatalogReplicaLoadBalanceSimpleSelector > --------------------------------------------------------------------------------------- > > 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 > Fix For: 2.5.0, 3.0.0-alpha-3, 2.4.12 > > > 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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
