With the acceleration development of the Internet of Things and big data, the importance of high-performance mass data retrieval is gradually highlighted. Cloud computing is the distributed data calculation model that is suitable for big data, and has been widely used. In this paper, firstly, the technology of cloud computing is introduced. Secondly, retrieval technology of mass data is analyzed, finally a high-performance retrieval method of mass data based on Hadoop is proposed. The architecture of this method is composed of HDFS, MapReduce, and Hive, and is divided into four layers from bottom to top: access layer, interface layer, management layer and storage layer.
