Sorry, I think it is a test case issue.
```
testData = Seq((1, 2), (2, 2), (3, 4), (null.asInstanceOf[Int],
5)).toDF("a", "b")
```
Scala automatically converts null.asInstanceOf[Int] into zero. Thus, Spark
treats it as zero. Never mind. I tried another way, like
null.asInstanceOf[java.lang.Integer]. It works fine.
