EMR作业从文件存储路径（例如，sparkOutput/walk_output_table）可以注意到，在hdfs:///sparkOutput/walk_output_table/issue_date_year=2019/sub_product_type=Student/industry_type=Bank/subject_key_partition=4/part-00144-af3420c7-85f3-4878-a039-1ee3a50bcb76.c000.snappy.parquet位置有多个分区的hdfs中写出了HDR。试图在各种变体中使用--srcPattern标签，甚至只是尝试复制一个文件而没有运气。下面是一个示例，出于隐私原因，baseBucket是组成的存储桶名称：
s3-dist-cp --src hdfs:///sparkOutput/walk_output_table --dest s3://baseBucket/output/hive/staging.3/loan_processed.4/append_month=2019-02-28 --srcPattern .*\.snappy.parquet --s3ServerSideEncryption
