Drew Farris commented on MAHOUT-401:
------------------------------------

Should I open another issue for the optional NamedVector creation? I might get to this one this week too.

> 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?
