-------------------------------------
Summary: MirrorMaker creates duplicate messages in target cluster
Key: KAFKA-10183
URL: https://issues.apache.org/jira/browse/KAFKA-10183
Project: Kafka
Issue Type: Bug
Components: mirrormaker
Affects Versions: 2.5.0, 2.4.0
Environment: Centos7.7
Reporter: Liraz Sharaby
Issue: Mirror maker creates a consumer-producer pair per server listed in
bootstrap.servers (mirrormaker config), resulting in duplicate messages in
target cluster.
When specifying 3 bootstrap servers, target topic will have 3 times the
messages its source does.
When specifying a single bootstrap server, only 1 consumer-producer pair is
created, and message count is identical in source and target topics.
