Huaxiang Sun commented on HBASE-26649: -------------------------------------- Seems something is wrong, checking with the latest code. > 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. -- This message was sent by Atlassian Jira (v8.20.7#820007)
