我正在运行一个使用 kafka 库的 java 程序，并每 1 秒检查一次来自 zookeeper 的消费者组的提交偏移量。程序运行良好约 2 小时并开始抛出 RuntimeException：

java.lang.RuntimeException: Error fetching offset data. Reason: 1
    at com.pinterest.secor.common.KafkaClient.getMessage(KafkaClient.java:127)
    at com.pinterest.secor.common.KafkaClient.getCommittedMessage(KafkaClient.java:186)

...

原因1是什么？我找不到任何文件或页面来说明这种情况的根本原因。

看看这个，这是一个代码片段kafka.common.ErrorMapping：

  val UnknownCode : Short = -1
  val NoError : Short = 0
  val OffsetOutOfRangeCode : Short = 1
  val InvalidMessageCode : Short = 2
  val UnknownTopicOrPartitionCode : Short = 3
  val InvalidFetchSizeCode  : Short = 4
  val LeaderNotAvailableCode : Short = 5
  val NotLeaderForPartitionCode : Short = 6
  val RequestTimedOutCode: Short = 7
  val BrokerNotAvailableCode: Short = 8
  val ReplicaNotAvailableCode: Short = 9
  val MessageSizeTooLargeCode: Short = 10
  val StaleControllerEpochCode: Short = 11
  val OffsetMetadataTooLargeCode: Short = 12
  val StaleLeaderEpochCode: Short = 13
  val OffsetsLoadInProgressCode: Short = 14
  val ConsumerCoordinatorNotAvailableCode: Short = 15
  val NotCoordinatorForConsumerCode: Short = 16
  val InvalidTopicCode : Short = 17
  val MessageSetSizeTooLargeCode: Short = 18
  val NotEnoughReplicasCode : Short = 19
  val NotEnoughReplicasAfterAppendCode: Short = 20

如您所见，1表示OffsetOutOfRangeCode.
