Hi @eminency, I left some comments.
In addition, I found the below error when I start a tajo cluster. I put the
hive udf jar file on hdfs and specified it in tajo-site.xml.

> Allow Tajo to use Hive UDF

> 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.
