In recent ten years,the rapid development of the automobile industry led to the car sales rising.As discovered by the China automobile industry association,the amount ofcar salesis more than 23 million in 2014 andthe expected car sales will further increasein 2015.As the development of network communication technology and automobile industry,the mode of car sales changed,the sales channel of the automobile has gradually shifted from the single traditional sales model to the online transaction.This kind of sales channels reduce people pre purchase car cost,the user can online purchase according to other people's review of car.At the same time it also brings the problem of overload amount of network information,consumers discover the needed information from the vast amount of information becomes more and more difficult,further increase the difficulty of the user to buy a car.The purpose of this paper is to develop a product recommendation systemwhich help consumers to find the needed information from the massive informationand recommend products satisfy the user requirements.This recommendation system is based on data acquisition module,data processing module,data warehouse and user oriented automotive recommendationsystem.Each module work together to achieve the function of each part of the system.The solution of this paper is based on the Hadoop cloud computing platform,providing a distributed file system and distributed computing framework for the system,and data warehouse provide decision support for the user to purchase a car.This paper first introduced thistopic research background and significance,research status and related technologies.The operation principle and process of the technology are analyzed.The source and characteristics of the mechanical product transaction data and the reasons for the selection of the car review data are summarized.Then this paper proposed the requirementsand designed the overall module of therecommendation system.Finally this paper built therunning system environment and realized the functional modules of the system.
