      The new encryption options SSE-KMS and especially SSE-C must be considered experimental at present. If you are using SSE-C, problems may arise if the bucket mixes encrypted and unencrypted files. For SSE-KMS, there may be extra throttling of IO, especially with the fadvise=random option. You may wish to request an increase in your KMS IOPs limits.

    Description

      S3 provides 3 types of server-side encryption [1],

      • SSE-S3 (Amazon S3-Managed Keys) [2]
      • SSE-KMS (AWS KMS-Managed Keys) [3]
      • SSE-C (Customer-Provided Keys) [4]

      Of which the S3AFileSystem in hadoop-aws only supports opting into SSE-S3 (HADOOP-10568) – the underlying aws-java-sdk makes that very simple [5]. With native support in aws-java-sdk already available it should be fairly straightforward [6],[7] to support the other two types of SSE with some additional fs.s3a configuration properties.
