spark on yarn cluster模式，异常：NoSuchMethodError: org.apache.kafka.clients.consumer.KafkaConsumer
异常出现
咱们能够看到在org.apache.spark.streaming.kafka010.InternalKafkaConsumer找不到对应的类java
解决方法：
由于spark对应kafka有版本要求，咱们在CDH的spark中搜索kafka
而后选择0.10
保存以后，而后重启下Spark
部署以后，从新执行命令mysql
spark2-submit \
--master yarn \
--deploy-mode cluster \
--class com.bigdata.PreWarningScalaAppV2 \
--jars /var/lib/hadoop-hdfs/converter-moshi-2.1.0.jar,/var/lib/hadoop-hdfs/fastjson-1.2.58.jar,/var/lib/hadoop-hdfs/guava-20.0.jar,/var/lib/hadoop-hdfs/influxdb-java-2.5.jar,file:/var/lib/hadoop-hdfs/kafka-clients-2.0.0.jar,file:/var/lib/hadoop-hdfs/logging-interceptor-3.5.0.jar,file:/var/lib/hadoop-hdfs/moshi-1.2.0.jar,file:/var/lib/hadoop-hdfs/okhttp-3.5.0.jar,file:/var/lib/hadoop-hdfs/okio-1.11.0.jar,file:/var/lib/hadoop-hdfs/retrofit-2.1.0.jar,file:/var/lib/hadoop-hdfs/spark-streaming-kafka-0-10_2.11-2.4.4.jar,file:/var/lib/hadoop-hdfs/mysql-connector-java-5.1.48.jar \
--conf "spark.driver.userClassPathFirst=true" \
/var/lib/hadoop-hdfs/prewarning-1.0.jar
