> h1. UC-5: S3 Integration
> While the Knox WebHDFS integration may still work for many cloud deployments, 
> it does seem like a gap that there is no way to move files in and out of S3 
> or other cloud storage mechanisms through Knox.
> We can actually combine UC-2 above to acquire temporary credentials on behalf 
> of the authenticated users. We would request the IAM role and permissions 
> that are appropriate for the user and their group memberships in order to 
> access buckets protected with IAM roles. We could also combine with UC-4 
> above to have encrypted files put into S3 that will only be able to be 
> decrypted on-prem.
> It would require Knox to be granted permission in a given cloud deployment to 
> make STS calls and may require AWS credentials for the Knox user to be an IAM 
> role. We may also be able to assumeRole to the needed role for STS access.
> It will also require a Jersey service hosted in Knox to put files into S3 
> (KnoxS3?) or we can create a pluggable backend and make it a more generic 
> object store API.
