SpletMapReduce Framework Sawsan M. Mahmoud Mustansiriyah University/College of Engineering, Computer Engineering Department, Baghdad, Iraq Email: [email protected] A MapReduce framework (or system) is usually composed of three operations (or steps): Map: each worker node applies the map function to the local data, and writes the output to a temporary storage. A master node ensures that only one copy of the redundant input data is processed.
