Mattew, Do you still put your source code in the io package and mapred package ?
If so, rebuild and hadoop core (seems you have done), and then invoke the command bin/hadoop -jar hadoop-0.20.2-example.jar sort -libjars hadoop-core-0.20.2.jar(your new builded jar) other_arguments PS: I do not recommend you to put your code mixed with hadoop code, it's better to put it another places, and build an individual jar.
