Swarnim Kulkarni updated HIVE-10697:
------------------------------------
Description:
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:
