Google introduced the MapReduce algorithm to perform massively parallel processing of very large data sets using clusters of commodity hardware. MapReduce is a core Google technology and key to ...

Originally the MapReduce algorithm was essentially hardwired into the guts of Hadoop’s cluster management infrastructure. It was a package deal: big data pioneers had to take the bitter with the ...

Some algorithms translate poorly to Map-Reduce—the partitioning of data and computation to individual nodes makes some computations (graph processing for instance) difficult. And, the implementation ...
