      Description

      GenericUDFs are very poorly documented, this includes everything they relate to:

      • ObjectInspector (JavaDoc not really helpful for someone not familiar with Hive)
      • ObjectInspectorFactory
      • ObjectInspectorConverters
      • ...

      An example would help as well as a unit test for one of the built in GenericUDFs. Writing a normal UDF is pretty well documented but GenericUDFs (and UDTF/UDAF) require more knowledge about the inner workings of Hive and that could be documented better.
