[jira] Created: (HADOOP-4229) Hive: UDFTemplate and support of
complex object
Hive: UDFTemplate and support of complex object
-----------------------------------------------
Key: HADOOP-4229
URL: https://issues.apache.org/jira/browse/HADOOP-4229
Project: Hadoop Core
Issue Type: Improvement
Reporter: Zheng Shao
Assignee: Zheng Shao
We should allow users to define UDF template (in the sense of c++ template that can take args of different types), and let UDF take complex objects.
This should be pretty simple given that we have the ObjectInspector which can navigate through the internal structure of the object.
