为什么我的消费者每次都要阅读主题中的所有消息，即使auto.offset.reset=largest？

我在topic1上给Kafka发了5条信息，并成功地将它们消费掉。当我发送第6条消息并尝试消费时，我再次收到所有6条消息，而不是最新的（第6条）消息。
请注意，我运行的是consumer命令行，而不是数据库连接器（access模块）。连接器的配置属性auto.offset.reset设置为“最大”。（请查看下面日志中的所有配置属性）
另请参见下面的offsetchecker输出：

bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker \
    --group testjob --zookeeper localhost:2181 --topic topic1
[2017-07-06 21:57:46,707] WARN WARNING: ConsumerOffsetChecker is deprecated and will be dropped in releases following 0.9.0. Use ConsumerGroupCommand instead. (kafka.tools.ConsumerOffsetChecker$)
Exiting due to: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /consumers/testjob/offsets/topic1/0.

谁能告诉我问题出在哪里吗？
