[jira] [Created] (HBASE-11442) ReplicationSourceManager doesn't
cleanup the queues for recovered sources
Virag Kothari created HBASE-11442:
-------------------------------------
Summary: ReplicationSourceManager doesn't cleanup the queues for recovered sources
Key: HBASE-11442
URL: https://issues.apache.org/jira/browse/HBASE-11442
Project: HBase
Issue Type: Bug
Components: Replication
Reporter: Virag Kothari
Assignee: Virag Kothari
Currently, ReplicationSourceManager only cleanups the queues for recovered sources when the queue is being closed. This can cause the already read WAL's files to be read again when a region server doing failover also dies. This can cause replication to possibly happen again
For e.g lets say RS1 dies with 5 files in queue and RS2 is doing the failover. Now, lets say RS2 dies after going thru 3 files in queue and RS3 is doing the failover. In this case, RS3 will again read those 3 files as they were not removed from the queue. (Though it will read the first file from the set pos. in ZK)
