Subject Q: Sending output of reduce to mapper
Date Sun, 07 Oct 2007 03:54:54 GMT


As a beginner of Hadoop, I wonder how to send output key-value pairs of the
reducers back to the input of mappers for iterative processing.  

What's hadoop streaming?  Can I pipe the output stream of reducers back to
the input stream of the mappers to achieve what I want?

Any pointer would be greatly appreciated.
