I'd suggest trying out the framework and writing some example code.  
The best things to contribute are things that are bothering you.  
*smile* I'd also suggest starting small and working up.

If you have spare cycles, it would be great if someone went through  
and made sure that all of the webapps using HtmlQuoting to quote all  
of the values that come from the jobs in the mapreduce webui.

Another nice one would be to implement another quoter for streaming  
that does:

tab -> \t
newline -> \n
return -> \r
slash -> \\

and leaves everything else alone. That would let streaming  
applications use binary data with a much simpler translation than  
typedbytes. See MAPREDUCE-606.
