Apache spark 试图在本地模型中提交spark应用程序，出现以下错误''；无法从JAR加载主类"；

我试图提交一个火花申请在我的本地和我下面的错误

Exception in thread "main" org.apache.spark.SparkException: Cannot load main class from JAR file:        at org.apache.spark.deploy.SparkSubmitArguments.error(SparkSubmitArguments.scala:657)

您是否尝试将master传递给命令

spark submit--master local word count.py

Yes@undefined_变量，我尝试了spark submit--master local word-count.py，仍然得到了相同的错误，您需要使用--py files命令行参数来传递py文件。我从未在spark上使用python。另一方面，您是否构建了一个包含python文件的JAR文件？我尝试了--py files参数，仍然面临相同的错误，我没有为.py文件构建JAR

from pyspark.sql import SparkSession
from pyspark.sql.functions import explode
from pyspark.sql.functions import split

def main():
    sparkSession = SparkSession.builder.appName("Word Count").getOrCreate()
    sparkSession.sparkContext.setLogLevel("ERROR")
    readStream = sparkSession.readStream.format('text').load(path)

    print("-------------------------------------------------")  
    print("Streaming source ready: ", readStream.isStreaming)
    readStream.printSchema()

    words = readStream.select(explode(split(readStream.value,'  ')).alias('word'))
    wordCounts = words.groupBy('word').count().orderBy('count')

    query = wordCounts.writeStream.outputMode('complete').format('console').start().awaitTermination()

if __name__ == '__main__':
    main()
