> If start field and end field are the same, parser doesn't take into account the sign before interval literal string. For example:
> Works fine:
> {code:sql}
> spark-sql> select interval -'1-1' year to month;
> -1-1
> {code}
> Incorrect result:
> {code:sql}
> spark-sql> select interval -'1' year;
> 1-0
> {code}
