Weka 3: Data Mining Software in Java
http://www.cs.waikato.ac.nz/ml/weka/index.html

Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes. Found only on the islands of New Zealand, the Weka is a flightless bird with an inquisitive nature. The name is pronounced like this, and the bird sounds like this. Weka is open source software issued under the GNU General Public License. They have put together several free online courses that teach machine learning and data mining using Weka. Check out the website for the courses for details on when and how to enroll. The videos for the courses are available on Youtube. Yes, it is possible to apply Weka to big data!
