I thought it'll be a quick fix, but it seems that I might be missing some larger context. Here's what I found so far. At some point there was a commit for MAHOUT-991 (1304490) that was supposed to converted MeanShift to emit ClusterWritable. Yet, if I run mahout with Hadoop in local mode under debugger it seems that the record reader returns key/value pairs with the value still being of type MeanShiftCanopy. I suppose that is understandable since the initial step in: org.apache.mahout.clustering.conversion.meanshift.InputDriver outputs MeanShiftCanopy and not anything else. After that the MeanShiftCanopyMapper sees MeanShiftCanopy when its map method is called and gets unhappy. Now, given that I'm still pretty new to Mahout development, I'm not quite sure what the proper fix here should be. Thoughts? Thanks, Roman.
