Hi Tao, Yes this is the intended behavior, since it only queries the consumer coordinator's in-memory cache about the consumer group metadata, which only contains active consumer groups, if a group has no live members any more it is treated as dead and removed from cache.
To get committed offsets from all groups that has not expired you can use console consumer to directly fetch the offset topic from Kafka: bin/kafka-console-consumer.sh --consumer.config config/consumer.properties --from-beginning --topic __consumer_offsets --zookeeper localhost:2181 --formatter "kafka.coordinator.GroupMetadataManager\$OffsetsMessageFormatter" Guozhang On Wed, Nov 25, 2015 at 4:53 AM, tao xiao <xiaotao...@gmail.com> wrote: > Hi team, > > In 0.9.0.0 a new tool kafka-consumer-groups.sh is introduced to show offset > and lag for a particular consumer group prefer over the old > one kafka-consumer-offset-checker.sh.
