> 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.
> NOTE : Have attached the Kafka Docker file, the mirror maker 2 logs and
> mirror maker 2 properties file. Also, have attached the describe command
> output of all the consumer groups present in source and destination.
