SortedTableSplitComparable which is a writable comparable required in OrderedLoadFunc is an inner class of SortedTableSplit. As a result, reflection fails and exception is thrown. To make it work, SortedTableSplitComparable may need to move into its own class with public visibility.

The OrderedLoadFunc clearly asks the implementation to instantiate any instance that conforms to WritableComparable interface, with which, I don't understand why Pig needs to use reflection to instantiate Zebra objects. Ideally, all matters is the interface and Pig shouldn't care how the underlying layer implements an interface or instantiate an object. Am I missing anything here?
