Apache Mahout

Amazon EMR supports Apache Mahout, a machine learning framework for Apache Hadoop. For more information about Mahout, go to http://mahout.apache.org/.

Mahout is a machine learning library with tools for clustering, classification, and several types of recommenders, including tools to calculate most-similar items or build item recommendations for users. Mahout employs the Hadoop framework to distribute calculations across a cluster, and now includes additional work distribution methods, including Spark.

For more information and an example of how to use Mahout with Amazon EMR, see the Building a Recommender with Apache Mahout on Amazon EMR post on the AWS Big Data blog.
