For Mahout 0.7, the format of the model files for LDA are just a
SequenceFile<IntWritable, VectorWritable>, with the row numbers being the
topicIds, and the entries being the (un-normalized) probabilities for each
termId.
bin/vectordump --dictionary <path to dictionary file> \
--dictioanryType <either text or sequencefile> \
--input <path to model files> \
--vectorSize <num entries per topic you want to
see> \
--sortVectors
