> In seq2sparse, TFIDFPartialVectorReducer and TFPartialVectorReducer should write NamedVectors.
It appears that a lack of labels on the vector input to k-means at least breaks the cluster-dumper
in the sense that it no longer prints the original document ids for points.

> I wonder if this is also an issue with the code that generates vectors from lucene indexes?
