> Currently one PigSplit wraps one to many input split and pig assign one
> PigSplit to one mapper; however when it serializes the split class name, it
> expects all input split to be of same class, hence it serializes class name
> only once --- the first split (see code snippet at the end).
> To support PigSplit wrap multi split class, we can serialize each split along
> with its own class name. This would allow each split to be
> deserialized/restored correctly. Of course, LoadFunc would need to dispatch
> input split to appropriate record reader.
