Initially I was running two instance of my consumer app on two different ports without setting a group.  When my producer pushed a message to Kafka both instances of the consumer received the message successfully.  Now I am trying to run them in a single consumer group so only one instance processes each message.  I am setting the spring.cloud.stream.bindings.input.group property in the application.yml like the following:\r\n\r\n`spring:\r\n  cloud:\r\n    stream:\r\n      bindings: \r\n        input:\r\n          destination: orders\r\n          content-type: application/json\r\n          group: shipping-group         \r\n `\r\n\r\nHowever, both instances are still receiving a copy of each message.  I see the following in both instances' log files so it looks like the spring.cloud.stream.bindings.input.group property is being picked up correctly:\r\n\r\n`2016-05-10 15:27:21.337  INFO 97540 --- [           main] o.s.c.s.b.k.KafkaMessageChannelBinder$7  : Adding {message-handler:inbound.orders.shipping-group} as a subscriber to the 'bridge.orders' channel\r\n2016-05-10 15:27:21.338  INFO 97540 --- [           main] o.s.c.s.b.k.KafkaMessageChannelBinder$7  : started inbound.orders.shipping-group\r\n`\r\n\r\nI am checking the consumer groups in my Kafka like the following but don't see the consumer group \"shipping-group\" at all:\r\n\r\n`kafka_2.11-0.9.0.1$ bin/kafka-consumer-groups.sh --zookeeper localhost:2181 --list\r\n`\r\n\r\nAm I missing anything to set this up correctly?\r\n\r\nThanks!\r\n"}}
