Hi Marc, I have myself personally used pipes, but I found it's performance wasn't faster than Java (on the same issue). I also found a lack of documentation (e.g. I saw nothing about xdr).
What I'd like to see is an example where you're using pipes to pass a struct from a mapper to a reducer using xdr (I have used bit arrays/packed structures to pass data from a mapper to a reducer using native byte order since it's safe to assume that machines in a cluster would be heterogenous). Perhaps if pipes saw more exposure it'd be used more frequently.
