Abstract: big data” is a hot research field of information science and technology．Military intelligence data has typical "big data" features．Hadoop is a software framework based on Java for distributed density data processing and analysis．In order to make the intelligence information and data access meet the real-time requirements,improved the scheduling algorithm under the framework of Hadoop．Through a simple classification way,we realized the real-time intelligence data access request scheduling in a laboratory environment.

Key words: Hadoop,HDFS,Schedule method,Cloud storage
