我正在尝试在本地设置spark history配置服务器。我正在使用windows和pycharm进行pyspark编程。我可以在localhost:4040. 我所做的是：
spark-defaults.conf：（在这里我添加了最后三行。）

spark.eventLog.enabled      true
spark.history.fs.logDirectory   file:///D:///tmp///spark-events

运行历史服务器

成功运行pyspark程序后，我无法在spark history server web ui上查看作业详细信息。尽管服务器已启动。如下所示：

我已经使用过的参考资料：
windows:apache spark历史服务器配置
如何在windows上运行spark历史服务器
我使用的代码如下：

from pyspark import SparkContext,SparkConf
 from pyspark.sql import SparkSession
 conf = SparkConf().setAppName("madhu").setMaster("local")
 sc = SparkContext(conf=conf)
 spark = SparkSession(sc).builder.getOrCreate()

 def readtable(dbname,table):
     dbname = dbname
     table=table
     hostname = "localhost"
     jdbcPort = 3306
     username = "root"
     password = "madhu"
     jdbc_url = "jdbc:mysql://{0}:{1}/{2}?user={3}&password={4}".format(hostname,jdbcPort, dbname,username,password)
     dataframe = spark.read.format('jdbc').options(driver = 'com.mysql.jdbc.Driver',url=jdbc_url, dbtable=table).load()
     return dataframe

 t1 = readtable("db","table1")
 t2 = readtable("db2","table2")

 print(t2.show())
 spark.stop()

请帮助我如何实现同样的目标。我将提供所需的任何数据。
我还尝试了以下目录路径：

spark.eventLog.enabled      true
 spark.history.fs.logDirectory   file:///D:/tmp/spark-events
