             Summary: Casting to int from a JSON-parsed float rounds instead of truncating
                 Key: SPARK-19754
                 URL: https://issues.apache.org/jira/browse/SPARK-19754
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.0, 1.6.3
            Reporter: Juan Pumarino
            Priority: Minor


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}
