View Of Mapreduce: Programming Model, Methods, And Its Applications

In recent years, cloud computing as a new Internet application pattern is changing the way that people access information and services. And, MapReduce, as a large-scale data processing and distributed computing model, attracts wide attention from academia and industry, and plays a decisive role in the development of cloud computing. 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 researchers and users who concern on cloud computing and MapReduce.
