我试图从一个名为 world 从一个名为 hello . 当我使用boto3列出该目录的所有对象时，我可以看到几个部件文件（可能是由spark作业创建的），如下所示。

world/
world/_SUCCESS
world/part-r-00000-....json
world/part-r-00001-....json
world/part-r-00002-....json
world/part-r-00003-....json
world/part-r-00004-....json
world/part-r-00005-....json
world/part-r-00006-....json
world/part-r-00007-....json

我编写了以下代码来读取所有这些文件。

spark_session = SparkSession
            .builder
            .config(
            conf=SparkConf().setAll(spark_config).setAppName(app_name)
        ).getOrCreate()
hadoop_conf = spark_session._jsc.hadoopConfiguration()
hadoop_conf.set("fs.s3a.server-side-encryption-algorithm", "AES256")
hadoop_conf.set("fs.s3a.aws.credentials.provider", "org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider")
hadoop_conf.set("fs.s3a.access.key", "my-aws-access-key")
hadoop_conf.set("fs.s3a.secret.key", "my-aws-secret-key")
hadoop_conf.set("com.amazonaws.services.s3a.enableV4", "true")

df = spark_session.read.json("s3a://hello/world/")

得到以下错误

我试过了 "s3a://hello/world/*" 以及 "s3a://hello/world/*.json" 但仍然得到相同的错误。
仅供参考，我正在使用以下版本的工具：

pyspark 2.4.5
com.amazonaws:aws-java-sdk:1.7.4
org.apache.hadoop:hadoop-aws:2.7.1
org.apache.hadoop:hadoop-common:2.7.1

有人能帮我吗？
