----------------------------------------
Summary: Kafka 3.5.1 Mirror Maker 2 not translating the wrong
offsets in destination
Key: KAFKA-15564
URL: https://issues.apache.org/jira/browse/KAFKA-15564
Project: Kafka
Issue Type: Bug
Components: mirrormaker
Affects Versions: 3.5.1
Reporter: Hemanth Savasere
Attachments: MM2 3.5.1 Logs.txt, docker-compose.yml, mm2.properties
Issue : Mirror Maker 2 not replicating the proper consumer group offsets when
replication happens from source to destination kafka brokers
Steps to Reproduce :
# 1. Created 2 Kafka clusters locally using the attached docker-compose.yml
file. Was using the confluent platform 7.2.1 docker images
# 2. Had added the below section to create 20 topics produce randomly 1000 to
2000 messages in each topic, and then consume the same messages using
consumer-groups.
{code:java}
/etc/confluent/docker/run &
sleep 20
for i in {1..20}; do
kafka-topics --create --bootstrap-server kafka-1:9092
--replication-factor 1 --partitions 1 --topic topic$$i
done
for i in {1..20}; do
num_msgs=$$(shuf -i 1000-2000 -n 1)
seq 1 $$num_msgs | kafka-console-producer --broker-list kafka-1:9092
--topic topic$$i
done
for i in {1..20}; do
timeout 10 kafka-console-consumer --bootstrap-server kafka-1:9092
--topic topic$$i --group consumer-group$$i
done
wait
{code}
3. Ran the Mirror Maker 2 using the connect-mirror-maker.sh script after
downloading the Kafka 3.5.1 release binaries. Verified the latest version was
running and commitID 2c6fb6c54472e90a was shown in attached MM2 logs file.
