-------------------------------------
Summary: Message loss if mirror maker is killed with hard kill and
then restarted
Key: KAFKA-2747
URL: https://issues.apache.org/jira/browse/KAFKA-2747
Project: Kafka
Issue Type: Bug
Reporter: Geoff Anderson
I recently added simple failover to the existing mirror maker test
(https://github.com/apache/kafka/pull/427) and found that killing mirror maker
process with a hard kill resulted in message loss.
The test here has two single-node broker clusters, one producer producing to
the source cluster, one consumer consuming from the target cluster, and a
single mirror maker instance mirroring data between the two clusters.
mirror maker is using old consumer, zookeeper for offset storage
