Cannot auto-commit offsets for group console-consumer-79720 since the coordinator is unknown

[#1]

Hi, I'm using kafka service KAFKA-2.1.0-1.2.1.0.p0.115.

`kafka-console-consumer --topic test3 --from-beginning --zookeeper cdh-1:2181` works well.

`kafka-console-consumer --bootstrap-server cdh-1:9092 --topic test3 --from-beginning --zookeeper cdh-1:2181 --new-consumer`, however, keep throwing "cannot auto-commit offsets for group since the coordinator is unknown"

does anyone have any idea? thanks a lot.

This link solved my problem.
However, there's something wrong with the kafka failover.

Hi,

We are also getting similar error like below:

WARN Auto offset commit failed for group console-consumer-26249: Offset commit failed with a retriable exception. You should retry committing offsets. (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)

We have three node cluster. If we kill one of the Kafka node then remaining two nodes hang and continuely gave above message without consume any data.

If we bring up the down node again then all are trying to consume data without above warning/exception message.

we are using kafka 0.10.1.1 version and linux machine.

we are tried below consumer properties. But no luck.

enble.auto.commit = true
auto.commit.interval.ms = 1000

zhuangmz : we can't restart the cluster in production.It is not acceptable solutions at production environment. 

Any specific properties to resolve this group coordination.

Thanks in Adv.

Thanks
