> In the DistCp class, the DistCpOptions are private with no getter method allowing retrieval by subclasses. So a subclass would need to save its own copy of the inputOptions supplied to its constructor, if it wishes to override the createInputFileListing method with logic similar to the original implementation, i.e. calling CopyListing#buildListing with a path and input options.
> I propose adding to DistCp this method,
> {noformat}
>   protected DistCpOptions getInputOptions() {
>     return inputOptions;
>   }
> {noformat}
