> From SQL:2003, the NULLS FIRST and NULLS LAST options can be used to determine whether
nulls appear before or after non-null data values when the ORDER BY clause is used.
> SQL standard does not specify the behavior by default. Currently in Hive, null values
sort as if lower than any non-null value; that is, NULLS FIRST is the default for ASC order,
and NULLS LAST for DESC order.
