Multiplcation Of Two Numbers Using Java In Ubuntu Mapreduce Output

This document describes how to perform matrix multiplication using MapReduce on Hadoop. It involves the following steps 1. Installing Hadoop in standalone mode and configuring Java settings. 2. Developing MapReduce programs including mappers, reducers, and a driver class for matrix multiplication. The mapper outputs key-value pairs of matrix elements and the reducer calculates and sums the

Program executed on SDSC Comet Cluster, using XSEDE Login Special thanks to professor and XSEDE for making this possible Use the output from the Stage 1 Reducer and pass

As it seen in MatrixMultiply.java code below, in main method the configuration parameters are being set as well as the inputoutput directories of MapReduce job 2. Mapper class extends org.apache.hadoop.mapreduce.Mapper class and implements the map task described in Algorithm 1 and creates the pairs from the input files as it shown in the

It can be optimized using Strassen's Matrix Multiplication. Auxiliary Space On 2 Multiplication of Rectangular Matrices We use pointers in C to multiply to matrices. Please refer to the following post as a prerequisite of the code. How to pass a 2D array as a parameter in C? Java

Reduce Aggregare, summarize, filter or transform and then give the output. In this post, I'll explain how to accomplish a matrix multiplication task with map reduce model. There are two ways of doing this. In one Map and Reduce part, or using two Map and Reduce tasks. The latter one is like a natural join followed by grouping and aggregation.

I'm working on the matrix multiplication using mapreduce. I built a jar file using the code below. the code works perfectly fine with smaller matrices but when the files becomes large the mapping phase will stop at 67 then it will give me this errors below YarnChild.java158 mapreduce worked when I used a smaller matrix. I will post the
