Hi, I use Kafka 0.10 with ZK 3.4.6 and my consumers' offsets aren't stored in the __consumer_offsets topic but in ZK instead.
That happens whether I let the consumer commit automatically, or commit manually with enable.auto.commit set to false. Same behavior with `offsets.storage=kafka`, which isn't surprising as this configuration value is dropped in 0.10. `kafka-console-consumer --topic __consumer_offsets --zookeeper localhost:/kafka-exp --bootstrap-server localhost:9092` shows nothing while my program is committing offsets. Not sure it matters, but I consume the topic using a Spark 2.0.0 app. Is there anything specific I should do to store consumers' offsets in a Kafka topic instead of ZooKeeper? Thank you for you help!
