Naveen Gangam updated HIVE-10808:
---------------------------------
Attachment: HIVE-10808.patch
NullStructSerDeObjectInspector extends StructObjectInspector yet the Category
for this inspector is set to PRIMITIVE, it should be STRUCT instead. This
causes the ClassCastException because ObjectInspectorUtils blindly casts it to
PrimitiveObjectInspector if the Category is PRIMITIVE.
> Inner join on Null throwing Cast Exception
