> test("except") {
> val df_left = Seq(1, 2, 2, 3, 3, 4).toDF("id")
> val df_right = Seq(1, 3).toDF("id")
> checkAnswer(
> df_left.except(df_right),
> Row(2) :: Row(2) :: Row(4) :: Nil
> )
> }
> {noformat}
> This is the example.
> For `EXCEPT ALL`, we should output
> {noformat}
> Row(2) :: Row(2) :: Row(3) :: Row(4) :: Nil
> {noformat}
> For `EXCEPT DISTINCT`, we should output
> {noformat}
> Row(2) :: Row(4) :: Nil
> {noformat}
> Thus, the current master is wrong. The result it generates is
> {noformat}
> Row(2) :: Row(2) :: Row(4) :: Nil
> {noformat}
