According to the rapid growth of the scale of the data at present, the traditional model of data analysis based on stand-alone can't meet to the storage and processing of massive data. With the rise of big data technology, integrating the traditional method of data analysis with big data platform to improve the efficiency of data analysis has become a research direction. This paper analyzes the integration of offline data processing and the Hadoop HDFS, MapReduce, designs a large offline data analysis system platform based on Hadoop, and introduces the core function module.
