没有这样的文件或目录问题

Question

我想在pyspark中使用SQL表。我能看到斯帕克德这样

sparkDF
DataFrame[SPRAS: string, PRCTR: string, DATBI: string, KOKRS: string, KTEXT: string, LTEXT: string, MCTXT: string]

但是当我sparkDF.show公司（）我得到一个错误。这是我的密码

import pyodbc
import pandas
import os

import findspark as fs
fs.init()
os.environ["JAVA_HOME"] = "C:/Program Files/Java/jdk1.8.0_181"
os.environ["PYTHONPATH"]=os.environ["PYTHON"]
from pyspark import SparkContext, SparkConf

conf = SparkConf().set("spark.cores.max", 3).set("spark.executor.memory", "3G").setAppName('hello').setMaster(
    'spark://xx.xx.xx.xx:7077')
sc = SparkContext(conf=conf)

sqlContext = SQLContext(sc)
spark = sqlContext.sparkSession

conn = pyodbc.connect('Driver={SQL Server};'
                      'Server=xx.xx.xx.xx;'
                      'Database=DEP;'
                      'Trusted_Connection=yes;')
sql = 'SELECT * FROM dep.xxxx'
pdf  = pandas.read_sql(sql, conn)
rdd=sc.parallelize(pdf)
sparkDF =  spark.createDataFrame(rdd)
sparkDF.show()
sparkDF.createOrReplaceTempView("sparkDF")
sqlDF = spark.sql("SELECT * FROM sparkDF")
sqlDF.show()

结果

9/11/21 09:42:45 WARN TaskSetManager: Lost task 0.0 in stage 12.0 (TID 63, xx.xx.xx.xx, executor 2): java.io.IOException: Cannot run program "C:\ProgramData\Anaconda3\envs\deneme\python.exe": error=2, No such file or directory

你知道这件事吗？（我是Python界的新人）
