| Abstract: | The key components of Hadoop are introduced first,then the MapReduce implementation mechanism is analyzed.What is more important,an application for statistics of employee salary is developed and the efficiency comparison is given in the three different applications,namely,the single node model,pseudo-distribution model and the full distribution model. |
