Abstract: The Japanese Virtual Observatory (JVO) portal is a web portal for accessing astronomical data and analysis system through the Internet. In the years of 2009 and 2010, we have developed two new access interfaces: JVOSky and command-line access interfaces. To enable users to perform all sky searches based on SED properties of celestial objects, we experimentally used the Hadoop for performing cross-match of one billion photometric records in the JVO Digital Universe.
