Cascading 3.0 proves we can abstract away the underlying platform by providing additional platforms users can execute against, not just MapReduce. Apache Tez is the first such addition. Tez is the latest parallel computation fabric from the Apache group. It builds on Hadoop, keeping the Hadoop File System for instance, but uses a model that removes inefficiencies that are baked into the MapReduce model.
