This is the home of the HAWQ subproject PXF.
PXF is an extensible framework that allows HAWQ to query external system data on HDFS. The framework is built in Java and provides built-in connectors for accessing data of various formats that exists inside HDFS files, Hive tables, HBase tables and many more stores.
Presentation on PXF http://www.slideshare.net/ShivramMani1/pxf-hawq-unmanaged-data
Users can also create their own connectors to other parallel data stores or processing engines. To create these connectors using JAVA plugins, see the HAWQ Extension Framework API Reference.
