What about the partitioner or combiner - C++ or Java?
Both the partitioners were in Java. There was no combiner.
Just wondering - there's got to be something that got subtracted.
I found what was happening. The Java sort application was setting the number of maps, so it was getting 400 maps instead of 320. Forcing it to 320 maps using "-m 320", I get numbers basically the same as pipes.
Java: 3:59, 4:03, 4:06 -- Owen
