原因分析
其实这个在官方文档中有介绍。地址如下：https://www.cloudera.com/documentation/spark2/latest/topics/spark2_kafka.html#running_jobs
方案一：错误信息中可以看出kafka的版本：Kafka version : 0.9.0-kafka-2.0.2，而我在pom.xml中应用的jar是0.10，因此导致包不一致。直接修改pom.xml对应jar版本号即可。
# Set the environment variable for the duration of your shell session: export SPARK_KAFKA_VERSION=0.10 spark-submit arguments # Or: # Set the environment variable for the duration of a single command: SPARK_KAFKA_VERSION=0.10 spark-submit arguments
方案二：就是kafka集成spark2，需要在CDH中进行设置。进入CDH的spark2配置界面，在搜索框中输入SPARK_KAFKA_VERSION，出现如下图，然后选择对应版本，这里我应该选择的是0.10，然后保存配置，重启生效。重新跑sparkstreaming任务，问题解决。
