卡夫卡消费群过期了吗?

Immediately after I commitoffset using the golang client. https://github.com/Shopify/sarama

./kafka-consumer-offset-checker.sh --zookeeper=localhost:2181 --topic=my-replicated-topic --group=ib --broker-info 

Group           Topic                          Pid Offset          logSize         Lag             Owner

ib              my-replicated-topic            0   12              12              0               none

BROKER INFO

1 -> localhost:9093

However, after several minute, I run the same checker command.

./kafka-consumer-offset-checker.sh --zookeeper=localhost:2181 --topic=my-replicated-topic --group=ib --broker-info 


Exiting due to: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /consumers/ib/offsets/my-replicated-topic/0.

And I check the zookeeper, the node never exists at any time, even when checker list the offset correctly.

sarama commit: 23d523386ce0c886e56c9faf1b9c78b07e5b8c90 kafka 0.8.2.1 golang 1.3

kafka server config:

broker.id=1
port=9093
num.network.threads=3
 num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/tmp/kafka-logs-1
num.partitions=1
num.recovery.threads.per.data.dir=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
log.cleaner.enable=false
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000

It seems to me that the consumer group get expired. How can I make the consumer group persist?

Sarama does not talk to zookeeper, I should use high level consumer group library instead.
