Work on HBASE-25211 started by Viraj Jasani. -------------------------------------------- > Rack awareness in region_mover > ------------------------------ > > Key: HBASE-25211 > URL: https://issues.apache.org/jira/browse/HBASE-25211 > Project: HBase > Issue Type: Improvement > Reporter: Viraj Jasani > Assignee: Viraj Jasani > Priority: Major > > region_mover should provide an option to ensure while unloading all regions, > all destination servers are selected from different racks and not the one > where server (where region_mover unload is getting executed) belongs to. This > might be helpful option if we want to avail rack downtime (or rack upgrade) > by stopping all Regionservers that belong to same rack for few hours. Without > this option, we don't have any control over which destination server is > selected and hence, some regions might keep bouncing from server A to B in > the same rack all the way until they are finally moved to RS that belongs to > separate rack. -- This message was sent by Atlassian Jira (v8.3.4#803005)
