The new Multipart Uploader API of
HDFS-13186 needs to work with S3Guard, with the tests to demonstrate this
- move from low-level calls of S3A client to calls of WriteOperationHelper; adding any new methods are needed there.
- Tests. the tests of
- test execution, with -DS3Guard, -DAuth
There isn't an S3A version of AbstractSystemMultipartUploaderTest, and even if there was, it might not show that S3Guard was bypassed, because there's no checks that listFiles/listStatus shows the newly committed files.
Similarly, because MPU requests are initiated in S3AMultipartUploader, encryption settings are't picked up. Files being uploaded this way are not being encrypted
