Wellington Chevreuil resolved HBASE-27551. ------------------------------------------ Resolution: Fixed Merged into master and branch-2. Thanks for reviewing it [~zhangduo][~swu]! > Add config options to delay assignment to retain last region location > --------------------------------------------------------------------- > > Key: HBASE-27551 > URL: https://issues.apache.org/jira/browse/HBASE-27551 > Project: HBase > Issue Type: Improvement > Reporter: Wellington Chevreuil > Assignee: Wellington Chevreuil > Priority: Major > Fix For: 2.6.0, 3.0.0-alpha-4 > > > HBASE-27313 introduced the ability to persist the list of files cached in a > given RS, but temporary RSes loss or restarts would cause regions to be > eagerly reassigned on other RSes, making the persisted cache useless. For > some use cases, such as when using ObjectStores based persistence, > performance degradation caused by cache misses have a worse impact than > temporary region unavailability. > This proposes and additional config property (disabled by default) to > forcibly wait the TRSP for a configurable time while checking for the > previous RS holding region to get back online, before proceeding with the > region assignment. -- This message was sent by Atlassian Jira (v8.20.10#820010)
