Summary: Region replicas of SPLIT and MERGED regions are kept in in-memory states until restarting master Key: HBASE-20049 URL: https://issues.apache.org/jira/browse/HBASE-20049 Project: HBase Issue Type: Bug Components: read replicas Reporter: Toshihiro Suzuki Assignee: Toshihiro Suzuki Currently, when regions are split or merged, region replicas of the regions will become CLOSED state but will not be deleted from in-memory states (e.g. AssignmentManager). These region replicas are deleted when restarting master, but I think they should be deleted during splitting and merging regions. One problem with this is the outdated region replicas can be online. Steps to reproduce are as follows: 1. Create a table with enabling region replication. {code} create "test", "cf", {REGION_REPLICATION => 2} {code} 2. Split the table {code} split "test" {code} 3. Disable and enable the table {code} disable "test" enable "test" {code} After doing those steps, the outdated region replica will be online. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
