It looks like you’re just missing the proper message formatter. Of course, that largely depends on your version of the broker. Try:
./kafka-console-consumer.sh --broker-list localhost:9092 --topic __consumer_offsets --formatter kafka.coordinator.GroupMetadataManager\$OffsetsMessageFormatter If for some reason that doesn’t work, you can try "kafka.server.OffsetManager\$OffsetsMessageFormatter” instead. -Todd On Sun, May 8, 2016 at 1:26 PM, Cliff Rhyne <crh...@signal.co> wrote: > I'm having difficulty reading the consumer offsets topic from the command > line.
