> Anti Join is broken when using BroadcastHashJoin's unique key path. For example:
> {noformat}
>   test("left anti join") {
>     val df = Seq(1, 3).toDF("int")
>     val df2 = Seq(1, 5).toDF("int2")
>     checkAnswer(
>       df.as("a").join(df2.as("b"), $"a.int" === $"b.int2", "left_anti"),
>       Row(3) :: Nil)
>   }
> {noformat}
> Returns {{df}} instead of an empty dataframe. Anti Join now behaves like a Semi Join.
