> BtJob uses a mixture of the old and new MapReduce API to allow it to use MultipleOutputs (which isn't available in Hadoop 0.20/1.0). This fails when run against 0.23 (see MAHOUT-822), so we should change BtJob to use the new MultipleOutputs API. (Hopefully the new MultipleOutputs API will be made available in a 1.x release - see MAPREDUCE-3607.)
