Question

我们将kafka版本从0.9更新到了2.0

需要帮助以找到合适的客户端库以进行Spark结构化流式传输

"org.apache.spark" %% "spark-streaming-kafka-0-10" % "2.3.0"

不起作用。

这是它引发的错误：

Answer 1

请提供更多信息（错误如何？！）。 Kafka经纪人被设计为向后兼容，这有助于大大落后于最新API（例如Spark）的项目。

您引用的spark-streaming-kafka-0-10的artifactId用于Spark Streaming，为了使用Spark Structured Streaming，您需要使用spark-sql-kafka-0-10_2.11

Kafka版本2的Spark结构化流
