The only JDBC related classes in Mahout are in the org.apache.mahout.cf.taste.* package to load a JDBCDataModel used for mining preferences. But I need Dataset and Instance which are used for building a decision tree (in org.apache.mahout.classifier.df.data). Can I somehow get these directly from the DB also with a standalone application without a Hadoop?
