Summary: 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 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)
