WebMatrix multiplication with MapReduce If A is an m × p matrix and B is an p × n matrix, then the product of A and B is the m × n matrix C = AB, where the ( i, j) th element of C is computed as the inner product of the ith row of A with the jth column of B: This is a dot product—simple arithmetic if m, p, and n are small. WebDec 22, 2024 · Map-Reduce is a programming model that is used for processing large-size data-sets over distributed systems in Hadoop. Map phase and Reduce Phase are the main two important parts of any Map-Reduce job. Map-Reduce applications are limited by the bandwidth available on the cluster because there is a movement of data from Mapper to …
