  Any comment(or examples) to share how to do that?  Thanks for your help.

I believe the hadoop *pipes* is what you need... it's coming up in the 
0.14.0 release in next few days:

http://svn.apache.org/viewvc/lucene/hadoop/trunk/src/java/org/apache/hadoop/mapred/pipes/package.html

Here is some context: http://issues.apache.org/jira/browse/HADOOP-234
