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"最大"。(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:

答案 0 :(得分:0)
添加此属性 AUTO_OFFSET_RESET_CONFIG =&#34;最早&#34;它会起作用
