> Key: KAFKA-5664

> Project: Kafka
> Issue Type: Improvement
> Reporter: Jason Gustafson
> Assignee: Vahid Hashemian
>
> In ConsoleCosnumer, if no group is provided, we generate a random groupId:
> {code}
> consumerProps.put(ConsumerConfig.GROUP_ID_CONFIG, s"console-consumer-${new Random().nextInt(100000)}")
> {code}
> In this case, since the group is not likely to be used again, we should disable automatic offset commits. This avoids polluting the coordinator cache with offsets that will never be used.
