To deal with the problem of semi-structure large XML data query processing which is difficult in single computer unit,Twig query structure matching features and Hadoop platform architecture are analyzed. The distributed store strategy is designed for XML data horizontal fragments on HDFS and parallel query method is implemented based on MapReduce program model through Twig query decomposition. The experimental results show that our approach is efficient and scalable on this problem.
