This extends the MapReduce programming model beyond batch processing, can reduce completion times and improve system utilization. Tyson included examples from the HOP - Hadoop Online Prototype project.

Bradford Cross: Flightcaster

Bradford Cross from Flightcaster provided an exciting overview on the FlightCaster flight delays prediction service and some cool insights into the airline industry. Bradford described how they built a scalable machine learning and data analysis platform using Clojure dynamic programming language wrapping Cascading and Hadoop. Bradford demonstrated how the use of Hadoop makes building scalable systems much simpler
