Thanks guys. The `seek` seems a solution. But it's more cumbersome than in 0.8 because I have to plug in some extra code in my consumer abstractions rather than simply deleting a zk node. And one more question: where does kafka 0.9 stores the consumer-group information? In fact I also tried to delete the consumer group but the `AdminUtils.deleteConsumerGroupInZK` does not seem to work in 0.9. And also `bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --zookeeper localhost:2181 --group group-name` seems broken.
