> Allow Tajo to use Hive UDF

> Key: TAJO-1686
> URL: https://issues.apache.org/jira/browse/TAJO-1686
> Project: Tajo
> Issue Type: New Feature
> Components: Function/UDF
> Reporter: Jaehwa Jung
> Assignee: Jongyoung Park
>
> 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.
