Question

我已经在topic1上向Kafka发了5条消息并成功使用了它们。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。

请注意我正在运行消费者命令行，而不是数据库连接器（访问模块）。连接器的配置属性auto.offset.reset设置为＆＃34;最大＆＃34;。（请参阅下面的日志中的所有配置属性）

另请参阅下面的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.

有谁能告诉我问题出在哪里？

以下是显示配置属性的日志：

Answer 1

添加此属性 AUTO_OFFSET_RESET_CONFIG =＆＃34;最早＆＃34;它会起作用

为什么我的消费者每次都会从主题中读取所有消息，即使auto.offset.reset = max？
