This is a common use case that can also serve to highlight feature extraction / 
feature encoding / 
feature encoding factories.

I committed what I have so far in r395. This is not completely tested, and in 
fact has definite problems with the 
full 20 newsgroups data set.

I added FeatureCollection and FeatureCollectionEncoder and modified Counts, 
then changed IDFMapWriter to 
make proper use of them. This should make it more useful, and I will try to 
build pipeline around it next.

These changes are committed in r826.

I rewrote the document classification example and it works and it is now clear 
what
should be run and in what order (i.e. Step1BuildIdfMap.java, etc.)  What 
remains is
to add a wiki on what is going on.  But this issue is closed.
