> Key: KAFKA-2857
> URL: https://issues.apache.org/jira/browse/KAFKA-2857
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Reporter: Ismael Juma
> Assignee: Ishita Mandhan
> Priority: Minor
>
> If we describe a non-existing group before the offset topic is created, like
> the following:
> {code}
> bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --new-consumer
> --describe --group gggg
> {code}
> We get the following error:
> {code}
> Error while executing consumer group command The group coordinator is not
> available.
> org.apache.kafka.common.errors.GroupCoordinatorNotAvailableException: The
> group coordinator is not available.
> {code}
> The exception is thrown in the `adminClient.describeConsumerGroup` call. We
> can't interpret this exception as meaning that the group doesn't exist
> because it could also be thrown f all replicas for a offset topic partition
> are down (as explained by Jun).
> Jun also suggested that we should distinguish if a coordinator is not
> available from the case where a coordinator doesn't exist.
