-------------------------------------
Summary: Add support for SSE-KMS and SSE-C in s3a filesystem
Key: HADOOP-13075
URL: https://issues.apache.org/jira/browse/HADOOP-13075
Project: Hadoop Common
Issue Type: New Feature
Components: fs/s3
Reporter: Andrew Olson
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 - the
underlying aws-java-sdk makes that very simple [5]. With native support in
aws-java-sdk it should be fairly straightforward [6],[7] to support these other
two flavors of SSE with some additional fs.s3a configuration properties.
