S3 中的服务器端和客户端加密(EMR 配置)

Server and client side encryption in S3 (EMR config)

快速简单的问题,但在文档中找不到任何内容:

在我的 emrfs-site.xml 中,我可以将 fs.s3.enableServerSideEncryptionfs.s3.cse.enabled 都设置为 true 吗?这会提供双重加密,还是不可能?

否,"Amazon S3 SSE and CSE are mutually exclusive; you can choose either but not both." http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-cluster-configuration-object-encryption.html
