> One solution that our users had is to write a new FileInputFormat, but that
> means all existing FileInputFormat subclasses need to be changed in order to
> support this feature.
> We can easily provide a JobConf option (which defaults to false) to
> {{FileInputFormat.listStatus(...)}} to recursively go into directory
> structure.
