> Support meta replica LoadBalance mode for
> RegionLocator#getAllRegionLocations()
> -------------------------------------------------------------------------------
>
> Key: HBASE-26649
> URL: https://issues.apache.org/jira/browse/HBASE-26649
> Project: HBase
> Issue Type: Improvement
> Components: meta replicas
> Affects Versions: 2.4.9
> Reporter: Huaxiang Sun
> Assignee: Huaxiang Sun
> Priority: Major
>
> When HBase application restarts, its meta cache is empty. Normally, it will
> fill the meta cache one region at a time by scanning the meta region. This
> will cause huge pressure to the region server hosting meta during application
> restart.
> It can prefetching all region locations by calling
> RegionLocator#getAllRegionLocations().Meta replica LoadBalance mode is
> support in 2.4, it will be nice to load balance
> RegionLocator#getAllRegionLocations() to all meta replica regions so batch
> scan can spread across all meta replica regions.
