Multiclass Classifer with Hadoop

I've been working large-scale hierarchical classification for the last few months or so. The 'large-scale' part of it was thankfully handled by the Opencloud Hadoop cluster which I got access to as a student of CMU. The large-scale I'm talking about here is primarily a large number of class-labels - the data however must still fit into main memory (for large training set sizes Cascade Support Vector Machines is a good alternative).
