pyspark连接mysql数据库报错

使用pyspark连接mysql数据库代码如下

spark_conf = SparkConf().setAppName("MyApp").setMaster("local")

spark = SparkSession.builder.config(conf=spark_conf).getOrCreate()

url = "jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&useSSL=false"
table_name = "tab_tf"
properties = {
    "user": "root",
    "password": "root"
}

# 读取 MySQL 数据库中的数据
df = spark.read.jdbc(url=url, table=table_name, properties=properties)
# 展示数据
df.show()

执行时报错了，错误信息如下：
