Designing good mapreduce algorithms

WebA MapReduce algorithm can be described by a mapping schema, which assigns inputs to a set of reducers, such that for each required output there exists a reducer that receives all the inputs participating in the computation of this output. Reducers have a capacity that limits the sets of inputs they can be assigned. WebA MapReduce framework (or system) is usually composed of three operations (or steps): Map:each worker node applies the mapfunction to the local data, and writes the output to a temporary storage. A master node ensures that only one …
