Wuheng Luo, Bo Liu, Allie K. Watfa · 2014
Big data in XML format poses a challenge to distributed data systems. This paper proposes an open Hive schema approach to XML data placement in Hadoop. Placing XML data in Hive with this generic schema to build column-oriented and OLAP-focused XML data warehouse of heterogeneous content has benefits for data access, maintenance and scalability.
