> {code}
> set hive.vectorized.execution.enabled=true;
> create temporary table xx (call_duration string, call_type string) stored as orc;
> insert into table xx values (null, "X"), ("0", "X"), ("1", "X"), (null, "y");
> SELECT
>    ROUND(sum(cast(COALESCE(call_duration, 0) as int))/60, 2) as SwitchMOU
> from xx
> GROUP BY call_type;
> {code}
> triggers the wrong cast, which results in a NULL, since the coalesce() has no resolved
return type - it is either a STRING or an INT.

> 0.02
> NULL
