Beijing University of Technology Tangyan

In order to establish mobile Terminal Cloud resource access mode in Hadoop architecture, the basic composition of Hadoop architecture is deeply understood, and the working principle of the core component HDFs Distributed File System and MapReduce distributed programming model is analyzed emphatically. The consistency of Hadoop and cloud computing in view and key technologies makes Hadoop a distributed cloud computing platform. Secondly, the cloud resource access mode is divided into three aspects: data storage strategy, request scheduling algorithm and data response mode, and the common cloud resource access pattern under Hadoop architecture is analyzed. Then, combined with the characteristics of small computation, high concurrency and high real-time demand, the mobile Terminal Cloud resource access mode based on Hadoop architecture is proposed. The data storage strategy includes the tree topology structure, the dynamic optimization model of replicas and the furthest node selection strategy, and proposes the farthest leaf node algorithm, which is used to obtain the farthest node, and a localization scheduling algorithm with the waiting length threshold is proposed in the request scheduling algorithm. The data response method uses the HTTP protocol to feed the results to the user. Finally, the access mode is applied to the tourism information retrieval system. Through the analysis of its application effect, it verifies that the access pattern not only saves storage space in the data storage strategy, but also improves the reliability of the file system, the localization scheduling algorithm greatly increases the probability of the request localization execution, shortens the request response time, and can easily feedback the request result to the user through the HTTP protocol.
