Kafka Error获取偏移数据。原因：1

Question

我正在运行一个使用kafka库的java程序，每隔1秒检查一次来自zookeeper的使用者组的已提交偏移量。 该程序运行良好约2小时，并开始抛出RuntimeException：

listener = threading.Thread(target=kbdListener)
listener.start()

...

1是什么原因？我找不到任何说明这种情况根本原因的文件或页面。

检查一下，这是kafka.common.ErrorMapping的代码片段：

  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。
