> Currently the UnionConvertor in the ObjectInspectorConvertors class has an
> issue with the convert method where it attempts to convert the
> objectinspector itself instead of converting the field.[1]. This should be
> changed to convert the field itself. This could result in a
> ClassCastException as shown below:
