Feng Honghua created HBASE-8357: ----------------------------------- Summary: current region server failover mechanism for replication can lead to stale region server whose left hlogs can't be replicated by other region server Key: HBASE-8357 URL: https://issues.apache.org/jira/browse/HBASE-8357 Project: HBase Issue Type: Bug Components: Replication Affects Versions: 0.94.3 Reporter: Feng Honghua
consider this scenario: rs A/B/C, A dies, B and C race to lock A to help replicate A's left unreplicated hlogs, B wins and successfully creates lock under A's znode, but before B copies A's hlog queues to its own znode, B also dies, and C successfully creates lock under B's znode and helps replicate B's own left hlogs. But A's left hlogs can't be replicated by any other rs since B left back a lock under A's znode and B didn't transfer A's hlog queues to its own znode before B dies. -- This message is automatically generated by JIRA.
