You can view ObjectWritable as an opaque container for any, well, Object ;). This means that you can produce Objects of whatever class (so long as they implement Writable), stuff them into ObjectWritables, and then write your own OutputFormat where you unpack them. Check e.g. SegmentMerger to see how to do this - this is an extreme case, because it not only produces different class types on output, but also produces many output files. -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com Using Tomcat but need to do more?
