从Apache Spark Kubernetes容器通过vpc端点发送400 Bad Request读写AWS S3.&

Question

我正在尝试通过vpc端点从Apache Spark Kubernetes container读写数据到AWS S3Kubernetes容器位于美国地区的本地(数据中心)。以下是连接到S3的Pyspark代码:

from pyspark.conf import SparkConf
from pyspark.sql import SparkSession
conf = (
SparkConf()
.setAppName("PySpark S3 Example")
.set("spark.hadoop.fs.s3a.endpoint.region", "us-east-1")
.set("spark.hadoop.fs.s3a.endpoint","<vpc-endpoint>")
.set("spark.hadoop.fs.s3a.access.key", "<access_key>")
.set("spark.hadoop.fs.s3a.secret.key", "<secret_key>")
.set("spark.hadoop.fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem")
.set("spark.driver.extraJavaOptions", "-Dcom.amazonaws.services.s3.enforceV4=true")
.set("spark.executor.extraJavaOptions","-Dcom.amazonaws.services.s3.enableV4=true")
.set("spark.executor.extraJavaOptions", "-Dcom.amazonaws.services.s3.enforceV4=true")
.set("spark.fs.s3a.path.style.access", "true")
.set("spark.hadoop.fs.s3a.server-side-encryption-algorithm","SSE-KMS")
.set("spark.hadoop.fs.s3a.aws.credentials.provider", "org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider")
)
spark = SparkSession.builder.config(conf=conf).getOrCreate()
data = [{"key1": "value1", "key2": "value2"}, {"key1":"val1","key2":"val2"}]
df = spark.createDataFrame(data)
df.write.format("json").mode("append").save("s3a://<bucket-name>/test/")

异常提出:

py4j.protocol.Py4JJavaError: An error occurred while calling o91.save.
: org.apache.hadoop.fs.s3a.AWSBadRequestException: doesBucketExist on <bucket-name>
: com.amazonaws.services.s3.model.AmazonS3Exception: Bad Request (Service: Amazon S3; Status Code: 400; Error Code: 400 Bad Request; Request ID: <requestID>; 

如有任何帮助，不胜感激

除非您的hadoop 3a客户端是区域感知的(3.3.1+)，否则设置该区域选项将不起作用。有一个aws sdk选项"aws.region，你可以把它设置为一个系统属性。
