Steve Loughran updated HADOOP-13075:
------------------------------------
Release Note: 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. (was: The new
encryption options SSE-KMS and especially SSE-C must be considered experimental
at present. The existing SSE-AWS mechanism is considered stable.)
> Add support for SSE-KMS and SSE-C in s3a filesystem

> 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.
