Apache Flink 将 BucketingSink 与 s3 集成

Question

能否使用Apache Flink自带的BucketingSink将数据写入s3？

我尝试了 URL 的几种组合，但我似乎无法使用 s3

例如s3://bucket/path/to/folder

当部署到 EMR 5.4.0 但不是 s3 时，我可以写入 hdfs。

文档没有提到 S3 作为潜在的集成，但我假设它是本地支持的。

https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/connectors/filesystem_sink.html

如果我使用 s3a:// url 格式，我会收到以下错误

EMR 做的事情与 ASF Hadoop 的 S3A 客户端不是 10% 兼容。坚持使用 Amaon 的 s3:// 网址：这是他们支持的网址
