You are using 0.20.203 but the documentation you are looking at is for 0.21. The MultipleOutputs and MultipleInputs were ported to the mapreduce context objects API in release 0.21. http://hadoop.apache.org/mapreduce/docs/r0.21.0/releasenotes.html
So it looks like you need to either: upgrade to 0.21 or use the old mapred.lib.MultipleOutputs API. Henry
