> -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-
> We need to support hive compatibility for all partition column types. But
> when using TIMESTAMP partition column, users might not get correct partitions
> occasionally because tajo partition name is different from hive partition
> name. Actually, Tajo automatically converts TIMESTAMP values to STRING
> literals which are accepted in the format YYYY-MM-DD HH:MM:SS. But Hive
> automatically converts it to STRING literals which are accepted in the format
> YYYY-MM-DD HH:MM:SS.MS.
