spark-submit提交任务报错：java.sql.SQLException:No suitable driver_spark no suitable driver

提交spark任务时一直报错:No suitable driver
提交任务命令如下

spark-submit \
--master yarn-client \
--num-executors 1 \
--executor-cores 2 \
--executor-memory 4G \
--conf spark.sql.shuffle.partitions=4 \
--class com.dy.ads.ads_rk_ccxx_population_property ../../script/smart-city-1.0.jar

每次执行这个命令都会报错，经过查询资料，尝试了加入--jars /opt/sparkJob/mysql-connector-java-5.1.47.jar也不行，后来又看到相关资料，还需要加入--conf spark.executor.extraClassPath=/opt/sparkJob/mysql-connector-java-5.1.47.jar才可以
完整命令如下
 

spark-submit \
--jars ../../jars/mysql-connector-java-5.1.37.jar \
--driver-class-path ../../jars/mysql-connector-java-5.1.37.jar \
--conf spark.executor.extraClassPath=/opt/sparkJob/mysql-connector-java-5.1.37.jar \
--master yarn-client \
--num-executors 1 \
--executor-cores 2 \
--executor-memory 4G \
--conf spark.sql.shuffle.partitions=4 \
--class com.dy.ads.ads_rk_ccxx_population_property ../../script/smart-city-1.0.jar

这三个必须都加上才可以，即--jars、--driver-class-path和--conf。
