-------------------------------------
Summary: MirrorMaker example in documentation does not work
Key: KAFKA-7314
URL: https://issues.apache.org/jira/browse/KAFKA-7314
Project: Kafka
Issue Type: Bug
Reporter: John Wilkinson
Kafka MirrorMaker as described in the documentation
[here|https://kafka.apache.org/documentation/#basic_ops_mirror_maker] does not
work. Instead of pulling messages from the consumer-defined
{{bootstrap.servers}} and pushing to the producer-defined
{{bootstrap.servers}}, it consumes and producers on the same topic on the same
host repeatedly.
To replicate, set up two instances of kafka following
[this|https://docs.confluent.io/current/installation/docker/docs/installation/recipes/single-node-client.html]
guide. The schema registry and rest proxy are unnecessary.
[Here|https://hub.docker.com/r/confluentinc/cp-kafka/] is the DockerHub page
for the image. The Kafka version is 2.1.0.
Using those two kafka instances, go {{docker exec}} into one and set up the
{{consumer.properties}} and the {{producer.properties}} following the
MirrorMaker guide.
Oddly, if you put in garbage unresolvable server addresses in the config, there
will be an error, despite the configs not getting used.
