> Currently at the end of a job FileSink operator moves/rename temp directory
> to another directory from which FetchTask fetches result. This is done to
> avoid fetching potential partial/invalid files by failed/runway tasks. This
> operation is expensive for cloud storage. It could be avoided if FetchTask is
> passed on set of files to read from instead of whole directory.
