Work Description: mehakmeet commented on pull request #2706:
URL: https://github.com/apache/hadoop/pull/2706#issuecomment-841783066
Had merge conflicts so had to force push.
Tests:
```
[ERROR] Tests run: 1430, Failures: 1, Errors: 34, Skipped: 538
```
Scale:
```
[ERROR] Tests run: 151, Failures: 3, Errors: 21, Skipped: 29
```
Most errors are MultiPart upload related:
```
com.amazonaws.SdkClientException: Invalid part size: part sizes for
encrypted multipart uploads must be multiples of the cipher block size (16)
with the exception of the last part.
```
Simply adding 16(Padding length) to multipart upload block size won't work.
The part sizes need to be a multiple of 16, so it has that restriction for CSE.
Also, one more thing to note here is that it assumes the last part to be an
exception, which makes me believe that multipart upload in CSE has to be
sequential(or can we parallel upload the starting parts and then upload the
last part?)? So, potentially another constraint while uploading could have
performance impacts here apart from the HEAD calls being required while
downloading/listing.

> Expose the client-side encryption option documented in Amazon S3
> documentation -
> http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingClientSideEncryption.html
> Currently this is not exposed in Hadoop but it is exposed as an option in AWS
> Java SDK, which Hadoop currently includes. It should be trivial to propagate
> this as a parameter passed to the S3client used in S3AFileSystem.java
