Subject [jira] [Commented] (HADOOP-13075) Add support for SSE-KMS and SSE-C in s3a filesystem
Date Fri, 14 Apr 2017 12:08:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15968944#comment-15968944
] 

Steve Loughran commented on HADOOP-13075:
-----------------------------------------

For people following this, HADOOP-14305 is covering what appears to be a serious issue here:
try running the encryption tests in parallel and things fail on getFileStatus() of directories.
That's potentially a blocker: I don't want to ship this feature until we understand what's
up and how make it go away. If its not fixable. we can discuss on that JIRA what to do next...maybe
diagnostics and docs are the solution. Step 1 though: work out what's going wrong.

> 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.
