I am using a kafka consumer where the partitions are assigned using maually instead of automatic group assignment using a code similar to "consumer. assign(<Partitions>);"
In this case bin/kafka-consumer-groups fails with the message "Consumer group `my_group1` does not exist or is rebalancing" On debugging I found that the AdminClient.scals is returning a empty list for the group summary with "GroupSummary(Dead,,,List())" status. The command works when I use a consumer group with automatic partition assignment. Can someone from kafka-dev confirm if this is the expected behaviour ? Thanks, Prabhu
