MapReduce is an approach to computing large quantities of data. This allows the workload to be distributed over a large number of devices. A structured way to apply this programming model is using the map and reduce.It takes a set of pairs of key/value inputs and generates a set of ...
Cloud Computing delivers computing resources so that it was appealing great thoughtfulness. Map Reduce is a programming model that be linked with the implementation for treating and creating large data sets. Since there is many drawbacks such as low scalability, does not support edible pricing and ...
Cloud ComputingData ProcessingParallel and Distributed ProcessingAn effective technique to process and analyse large amounts of data is achieved through using theMapReduce framework. It is a programming model which is used to rapidly process vast amount of datain parallel and distributed mode operating...

Aim to current status of MapReduce applications in cloud computing, this paper describes the MapReduce programming model and operation mechanism, and gives a typical application based on MapReduce. On this basis, several challenges and ideas for MapReduce are proposed to offer some references for ...
MapReduce is a programming system for distributed processing of large-scale data in an efficient and fault tolerant manner on a private, public, or hybrid cloud. MapReduce is extensively used daily around the world as an efficient distributed computation tool for a large class of problems, e.g...
Hadoop is capable of running MapReduce programs written in various languages: Java, Ruby, Python, and C++. The programs of Map Reduce in cloud computing are parallel in nature, thus are very useful for performing large-scale data analysis using multiple machines in the cluster. ...
the idea of trigram N-gram parallelization algorithm based on MapReduce programming model is proposed. In the MapReduce programming model, the arithmetic tasks are evenly distributed to m nodes. The main task of the trigram N-gram algorithm in the Map function part is to calculate the number ...
