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

Question

Does anyone come across the issue when assign auto.offset.reset->"latest" doesn't affect this property in spark-streaming-kafka 0-10

here is my code:

 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))

But when I deploy I get this results

Could you help please? Thanks

Answer 1

i am not sure why the setting is ignored but you could also try not to set the auto.offset.reset because the default is "latest" in the new consumer configs. Source of information: https://kafka.apache.org/documentation#newconsumerconfigs

Answer 2

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

@jpsjph 如果我们尽量不设置 auto.offset.reset，这个问题就解决了
