Are you looking for something like a "distributed grep?" The hadoop package comes with some examples, and 'grep' is one of them. Please see: http://wiki.apache.org/hadoop/Grep and http://hadoop.apache.org/common/docs/r0.20.2/quickstart.html . Let us know if you are looking for something else. -b > > > > I hope you don't mind my question.
