Я запускаю простое приложение spark, чтобы получить файл из s3 в rdd и преобразовать его в фрейм данных pyspark:
data=sc.textFile('s3a://bigdata-plat/churnData/transaction.csv')
df=data.toDF()
также пробовал,
data=sc.textFile('s3a://bigdata-plat/churnData/transaction.csv')
df = data.map(lambda x: Row(**f(x))).toDF()
, но выдает ту же ошибку:
java.lang.NoSuchMethodError: com.amazonaws.services.s3.transfer.TransferManager.<init>(Lcom/amazonaws/services/s3/AmazonS3;Ljava/util/concurrent/ThreadPoolExecutor;)V

Я устанавливаю контекст свечи как:
pyspark.SparkConf().setAll([('spark.eventLog.dir', '/spark/logs/tmp/')
,("spark.driver.extraClassPath","path/hadoop-common-2.7.7.jar:/path/aws-java-sdk-1.10.6.jar:path/hadoop-aws-2.7.7.jar")
,("spark.hadoop.fs.s3a.impl","org.apache.hadoop.fs.s3a.S3AFileSystem")
,("fs.s3a.access.key", AWS_ACCESS_KEY)
,("fs.s3a.secret.key", AWS_SECRET_KEY)])
Я использую Spark 2.4, hadoop 2.7.7
aws-java-sdk versions tried : 1.11.440, 1.11.75, 1.10.6, 1.7.4
Я не могу понятьвот это проблема зависимости?или мне не хватает каких-либо дополнительных файлов JAR, которые необходимылюбое решение?
