Question

在分配auto.offset.reset-＆gt;＆＃34;最新＆＃34;时，是否有人遇到此问题？不会影响spark-streaming-kafka 0-10中的这个属性

这是我的代码：

 val config = StreamingConfigHelper.getStreamingConfig()
val kafkaParams = Map[String, Object]("bootstrap.servers" -> config.brokers,
  "key.deserializer" -> classOf[ByteArrayDeserializer],
  "value.deserializer" -> classOf[ByteArrayDeserializer],
  "group.id" -> "prodgroup",
  "auto.offset.reset" -> "latest",
  "receive.buffer.bytes" -> (65536: java.lang.Integer),
  "enable.auto.commit" -> (false: java.lang.Boolean))
val inputDStream = KafkaUtils.createDirectStream[Array[Byte], Array[Byte]](streamingContext, LocationStrategies.PreferConsistent,
  ConsumerStrategies.Subscribe[Array[Byte], Array[Byte]](config.productTopic.toArray, kafkaParams))

但是当我部署时，我得到了这个结果

你可以帮忙吗？感谢

我不确定为什么忽略该设置但你也可以尝试不设置auto.offset.reset，因为新的消费者配置中的默认值是“最新的”。信息来源： https://kafka.apache.org/documentation#newconsumerconfigs

您的设置在KafkaUtils.fixKafkaParams中被覆盖：我不知道为什么......

spark-streaming-kafka-0-10 auto.offset.reset始终设置为none
