Preet Puri commented on STORM-2342:
-----------------------------------
Any update on this. Having similar issue. if I kill the topology and start it again, the same messages are being reprocessed. Don't see offset updated in Kafka/Zookeeper?

> Project: Apache Storm

> Priority: Critical

> I've created a topology that will read from kafka using storm-kafka-client but when it reaches the last message on kafka log it stops consuming and get stuck, new messages are never consumed, here are the kafka logs:
> {quote}
> [2017-02-03 19:15:26,865] INFO [GroupCoordinator 1002]: Preparing to restabilize group kafka-spout with old generation 29 (kafka.coordinator.GroupCoordinator)
> [2017-02-03 19:15:26,865] INFO [GroupCoordinator 1002]: Stabilized group kafka-spout generation 30 (kafka.coordinator.GroupCoordinator)
> [2017-02-03 19:15:26,868] INFO [GroupCoordinator 1002]: Assignment received from leader for group kafka-spout for generation 30 (kafka.coordinator.GroupCoordinator)
> {quote}
> ========= here storm starts consuming messages, then, when it hits the last message, I can see this log in kafka == >
> {quote}
> [2017-02-03 19:16:01,266] INFO [GroupCoordinator 1002]: Preparing to restabilize group kafka-spout with old generation 30 (kafka.coordinator.GroupCoordinator)
> [2017-02-03 19:16:01,266] INFO [GroupCoordinator 1002]: Group kafka-spout with generation 31 is now empty (kafka.coordinator.GroupCoordinator)
> {quote}

> and then storm consumer group is stuck, no new messages are read from kafka. my topology/ spout are configured that way:
> *Topology:*
> c.put(SConfig.TOPOLOGY_MAX_SPOUT_PENDING, 1000)
> c.put(SConfig.NIMBUS_SEEDS, "my nimbus seeds")
> c.put(SConfig.NIMBUS_THRIFT_PORT, 6627)
> c.put(SConfig.TOPOLOGY_WORKERS, 2) c.put(SConfig.TOPOLOGY_SLEEP_SPOUT_WAIT_STRATEGY_TIME_MS, 100)
> *Spout:*
> props.put(KafkaSpoutConfig.Consumer.ENABLE_AUTO_COMMIT, true)
> props.put(KafkaSpoutConfig.Consumer.BOOTSTRAP_SERVERS, ...)
> props.put(KafkaSpoutConfig.Consumer.GROUP_ID, "kafka-spout")
> props.put(KafkaSpoutConfig.Consumer.KEY_DESERIALIZER, keyDeserializer)
> props.put(KafkaSpoutConfig.Consumer.VALUE_DESERIALIZER, valueDeserializer)
>
> Also the offsets are not seeming to be committed, despite I've set *enable.auto.commit* and *auto.commit.interval.ms* properties, because if I kill the topology and send it again, the same messages are being reprocessed...
> any hints?
