I'm think I'm missing something. Could I use a SequenceFile<Integer,MultiLabelVectorWritable> as input to anything that takes SequenceFile<Integer,VectorWritable>? The get() method would continue to return a Vector of some sort. I have this vague recollection that hadoop has problems with this sort of subclassing, but I don't remember the details.
