partitions like part-00000, part-00001 ?]'''

+ You can subclass the [http://svn.apache.org/viewvc/hadoop/core/trunk/src/mapred/org/apache/hadoop/mapred/OutputFormat.java?view=markup
   OutputFormat.java] class and write your own. You can look at the code of [http://svn.apache.org/viewvc/hadoop/core/trunk/src/mapred/org/apache/hadoop/mapred/TextOutputFormat.java?view=markup
     TextOutputFormat] [http://svn.apache.org/viewvc/hadoop/core/trunk/src/mapred/org/apache/hadoop/mapred/MultipleOutputFormat.java?view=markup
   MultipleOutputFormat.java] etc. for reference. It might be the case that you only need
to do minor changes to any of the existing Output Format classes. To do that you can just
subclass that class and override the methods you need to change.
