Steve Loughran commented on HADOOP-18281:
-----------------------------------------

so the only remaining thing here is the idea of making this a createFile() 
option. Do we really perceive that as a need (alternatively: should these 
decisions be compiled into code?)

>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/s3
>    Affects Versions: 3.3.5
>            Reporter: Steve Loughran
>            Priority: Minor

> Followup to HADOOP-12020, with work/review from rebasing HADOOP-17833 atop it.
> * Can we merge ITestS3AHugeFilesStorageClass into one of the existing test 
> cases? just because it is slow...ideally we want as few of those as possible, 
> even if by testing multiple things at the same we break the rules of testing.
> * move setting the storage class into
> setOptionalMultipartUploadRequestParameters and 
> setOptionalPutRequestParameters
> * both newPutObjectRequest() calls to set storage class
> * docs to list the valid option strings. I had to delve into the AWS SDK to 
> work them out
> Once HADOOP-17833 is in, make this a new option something which can be 
> explicitly used in createFile().
> I've updated PutObjectOptions to pass a value around, and made sure it gets 
> down to to the request factory. that leaves
> * setting the storage class from the options {{CreateFileBuilder}}
> * testing!
> * doc update
