----------------------------------
Thank you for you time [~Srdo]]. I'll close this ticket since it's a
non-issue/expected behaviour.
Cheers
> Kafka Spout has no active members in consumer group
> ---------------------------------------------------
>
> Key: STORM-3067
> URL: https://issues.apache.org/jira/browse/STORM-3067
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-kafka-client
> Affects Versions: 1.1.2
> Reporter: Rui Abreu
> Priority: Major
>
> Using Kafka 10.2.1, two different behaviours were observed:
> Storm 1.1.0 =>
> {code}
> /opt/kafka/bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092
> --group test.topic.consumer-group --describe
> Note: This will only show information about consumers that use the Java
> consumer API (non-ZooKeeper-based consumers).
> TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID
> test.topic 0 85186604 85186607 3
> consumer-2-27a77d1b-e851-47a4-954e-4953ea612b72 /X.X.X.X consumer-2
> {code}
>
> Storm 1.1.2 =>
> {code:java}
> /opt/kafka/bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092
> --group test.topic.consumer-group --describe
> Note: This will only show information about consumers that use the Java
> consumer API (non-ZooKeeper-based consumers).
> Consumer group 'test.topic.consumer-group' has no active members.
> TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID
> test.topic 0 85202473 85202475 2 -{code}
> Despite this behaviour, the topology continues to consume messages and commit
> offsets to Kafka. It's unclear if this lack of active clients on the consumer
> group affects the normal functioning of the Spout.
