Hi @eminency, thanks for your work. It seems good overall.
I left some comments. In addition, would you briefly evaluate the
performance of Hive UDF call? I wonder how large its overhead is.
> Allow Tajo to use Hive UDF

> Key: TAJO-1686

> Hive has been widely used in this area. Many users have maintained lots of
> big tables through Hive metastore using HiveQL and UDFs. Currently, Tajo
> provides own UDF and Hive users can implement their UDFs in Tajo. But if we
> can wrap Hive UDF in Tajo, it seems that they would be able to use Tajo
> easily for their analysis infrastructure.
