	// NullWritable is a `Comparable` in Hadoop 1.+, so the compiler cannot find an implicit
	// Ordering for it and will use the default `null`. However, it's a `Comparable[NullWritable]`
	// in Hadoop 2.+, so the compiler will call the implicit `Ordering.ordered` method to create an
	// Ordering for `NullWritable`. That's why the compiler will generate different anonymous
	// classes for `saveAsTextFile` in Hadoop 1.+ and Hadoop 2.+.
	//
	// Therefore, here we provide an explicit Ordering `null` to make sure the compiler generate
