Some mahout algorithms use map-reduce, others (e.g. logistic regression) do not. If your data is in hive, you could look in to shoehorning the mahout algorithm in to a UDAF. This is what I'll be looking in to in the next couple of weeks, so if it's of potential interest, ping me in a few weeks and I'll give an update.
