> Some IO we want to be able to abort rather than close cleanly, especially if 
> the inner stream is an HTTP connection which itself supports some abort() 
> method. For example: uploads to an object where we want to cancel the upload 
> without close() making an incomplete write visible.
> Proposed: Add a generic interface which things like streams can implement
> {code}
> AbortableIO {
>   public void abortIO() throws IOE;
> }
> {code}
> +do for s3a output stream. I wouldn't do this a passthrough on 
> FSDataOutputStream because we need to consider what expectations callers have 
> of an operation being "aborted"
