>             Project: Flink
>          Issue Type: Improvement
>          Components: Core
>    Affects Versions: 1.3.1
>            Reporter: Stephan Ewen
>            Assignee: Stephan Ewen
>             Fix For: 1.4.0, 1.3.2
>
>
> Currently, all {{FileSystem}} types look the same to Flink.
> However, certain operations should only be executed on certain kinds of file 
> systems.
> For example, it makes no sense to attempt to delete an empty parent directory 
> on S3, because there are no such thinks as directories, only hierarchical 
> naming in the keys (file names).
