> Currently, Tajo allow to use TIMESTAMP column as a partition key. But if users use TIMESTAMP partition column, Tajo doesn't keep the original TIMESTAMP values. Actually, Tajo automatically converts TIMESTAMP values to STRING literals which are accepted in the format YYYY-MM-DD HH:MM:SS. As a result, Tajo can't keep mills of second and can't provide right hive compatibility
