Geoff Anderson created KAFKA-2747: ------------------------------------- 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
