Initially, I created a topic named "quickstart-events" and then produced some messages into it, then consumed it from the kafka-console-consumer with consumer group "quickstartGroup" and now I want to replicate the group from source to destination.
When I run describe command to describe the group in the source cluster ~/kafka/bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group quickstartGroup The output I'm getting is Consumer group 'quickstartGroup' has no active members. GROUP TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID quickstartGroup quickstart-events 1 9 12 3 - - - quickstartGroup quickstart-events 0 9 12 3 - - - - Here, the topic is getting replicated but when I run the command to describe the group in the destination cluster kafka-consumer-groups.sh --bootstrap-server localhost:9093 --describe --group quickstartGroup Getting error as Error: Consumer group 'quickstartGroup' does not exist My Mirror Maker 2 properties file contents are and I have also modified groups.exclude peoperty # Licensed to the Apache Software Foundation (ASF) under A or more # contributor license agreements.
