> As per ceil/ceiling definition,it should get BIGINT return value
> -ceil(DOUBLE a), ceiling(DOUBLE a)
> -Returns the minimum BIGINT value that is equal to or greater than a.
> But in current Spark implementation, it got wrong value type.
> e.g., 
> select ceil(2642.12) from udf_test_web_sales limit 1;
> 2643.0
> In hive implementation, it got return value type like below:
> hive> select ceil(2642.12) from udf_test_web_sales limit 1;
> OK
> 2643
