-------------------------------------
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)
