>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs, fs/s3, tools/distcp
>    Affects Versions: 3.3.0
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Major

>  Remaining Estimate: 0h
>
> The {{openFile()}} builder API lets us add new options when reading a file
> Add an option {{"fs.s3a.open.option.length"}} which takes a long and allows 
> the length of the file to be declared. If set, *no check for the existence of 
> the file is issued when opening the file*
> Also: withFileStatus() to take any FileStatus implementation, rather than 
> only S3AFileStatus -and not check that the path matches the path being 
> opened. Needed to support viewFS-style wrapping and mounting.
> and Adopt where appropriate to stop clusters with S3A reads switched to 
> random IO from killing download/localization
> * fs shell copyToLocal
> * distcp
> * IOUtils.copy
