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。
