      Description

      when casting incorrect date literals to DATE data type hive returns wrong values instead of NULL.

      SELECT CAST('2017-02-31' AS DATE);
      SELECT CAST('2017-04-31' AS DATE);
      
      

      Some examples below where it really can produce weird results:

      select *
        from (
      select cast('2017-07-01' as date) as dt
      ) as t
      where t.dt = '2017-06-31';
      
      select *
        from (
      select cast('2017-07-01' as date) as dt
      ) as t
      where t.dt = cast('2017-06-31' as date);
