SparkSql中jdbc连接mysql时候报错No suitable driver

在学习sparksql中连接jdbc报错
Exception in thread "main" java.sql.SQLException: No suitable driver
       at java.sql.DriverManager.getDriver(DriverManager.java:315)
       at org.apache.spark.sql.execution.datasources.jdbc.JDBCOptions$$anonfun$7.apply(JDBCOptions.scala:84)

       at scala.Option.getOrElse(Option.scala:121)

SparkSql中jdbc连接mysql时候报错No suitable driver最先出现在Python成神之路。
