> Terasort TeraOutputFormat does not check for output directory existance

> 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}}.
