> The enforcement that the directory must not yet exist is implemented in {{FileOutputFormat#checkOutputSpecs}} by throwing {{FileAlreadyExistsException}}.  However, terasort uses a specialized output format, {{TeraOutputFormat}}, which is a subclass of {{FileOutputFormat}}.  The subclass overrides {{checkOutputSpecs}}, but does not re-implement the existence check and throw {{FileAlreadyExistsException}}.
