Mahout logs via SLF4J, which is a sort of meta-logger. It logs to whatever log system you have in your classpath (by adding certain SLF4J bindings). So you configure *that* logging system.
By default I think it does nothing, so if you see the messages, you've got some logging bindings going, maybe the Java SDK logger? That's configured with a logging.properties file or command line params, and you can check the java.util.logging javadoc for detail.
