First, this paper talked about the deficiencies of current Equipment Support Management System on massive data query and analysis. Then it proposed and realized a method of Structured Data Query used by the Cloud Platform based on Hadoop, after analyzing the data source. In the article, we used the tool of Sqoop to import data from a relational database into HDFS, and then use Hive to analyze the data. Finally, the experiment proved that the method makes up the shortage of the data query in the environment of single computer, and has high practical value.
