Spark Streaming 写kafka报错:kafka.cluster.BrokerEndPoint cannot be cast to kafka.cluster.Broker

 写了一个spark 读写kafka任务，直接在idea 以local模式运行直接报错

报错:Caused by: java.lang.ClassNotFoundException: kafka.cluster.BrokerEndPoint

后来查看kafka包

       发现确实没有BrokerEndPoint，然后百度查看了一下，发现只有0.9版本才有。

       反复修改pom.xml文件，打包运行。错误就仍然照旧同样一条。修改pom.xml文件中，查看了下kafka0.9比0.8多了BrokerEndPoint类，可问题是maven的都是0.8版的。
      后来再到官网去看介绍发现

          http://spark.apache.org/docs/latest/streaming-kafka-0-8-integration.html

重点：spark-streaming-kafka-0-8_2.11需要2.4.0版本的，而我采用的是2.2.0版本的。
