对Spark和数据工程整体来说是全新的。我编写了一个Spark应用程序(在我的本地)，它打算使用Spark SQL将拼花文件推送到S3桶。我的代码此时在文件中失败了:
配置:
os.environ['AWS_ACCESS_KEY_ID'] = config['AWS']['AWS_ACCESS_KEY_ID']
os.environ['AWS_SECRET_ACCESS_KEY'] = config['AWS']['AWS_SECRET_ACCESS_KEY']
spark = SparkSession.builder
.config("spark.jars.packages", "org.apache.hadoop:hadoop-aws:3.2.0,com.amazonaws:aws-java-sdk:1.12.369")
.config('spark.hadoop.fs.s3a.aws.credentials.provider', 'org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider')
.getOrCreate()
失败的部分代码(其中calendar_dim等是spark。sql dataframes):
output_path = "s3a://i94immigration/"
calendar_dim.write.parquet(output_path + "calendar_dim", partitionBy=['year', 'month', 'week'], mode="overwrite")
us_demographics_dim.write.parquet(output_path + "us_demographics_dim", partitionBy='state_code', mode="overwrite")
us_airport_dim.write.parquet(output_path + "us_airport_dim", mode="overwrite")
country_dim.write.parquet(output_path + "country_dim", mode="overwrite")
immigration_fact.write.parquet(output_path + "immigration_fact", mode="overwrite")
完整错误:

py4j.protocol.Py4JJavaError: An error occurred while calling o865.parquet.

我可以确认我能够读取和写入简单的csv/txt文件到S3桶。此外，拼花工作对象是在写入本地存储时正常创建的。我已经做了很多谷歌/阅读，我不确定我在哪里出错了。希望能得到一些指导。
原来我使用的Hadoop版本存在依赖问题。将hadoop-aws版本更改为3.2.2为我解决了这个问题。
