>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.6.3, 2.1.0
>            Reporter: Juan Pumarino

>
> When retrieving a float value from a JSON document, and then casting it to an integer, Hive simply truncates it, while Spark is rounding up when the decimal value is >= 5.
> In Hive, the following query returns {{1}}, whereas in a Spark shell the result is {{2}}.
> {code}
> SELECT CAST(get_json_object('{"a": 1.6}', '$.a') AS INT)
> {code}
