> In GetItem, we will cast the ordinal into Int first. However, if the ordinal is Long type, execution will fail even the value of ordinal meets the requirement. The reason is boxing. In java, we can convert long to int, but can't convert Long to Integer.
> {code}
> test("get item") {
>   jsonRDD(sparkContext.makeRDD(
>     """{"a": [1,2,3], "b": 2}""" :: Nil)).registerTempTable("t")
>   checkAnswer(sql("SELECT a[b] FROM t"), Row(3))
> }
> {code}
> This test will fail as "b" is inferred as Long type.
