NVM. I just tried changing the hadoop version in the pom to 0.18.3 and it will not compile due to many new classes in Hadoop (Context, Reducer, BinaryComparable, ... the list goes on) that are referenced in our code. Should have tried that first. If it does work, I'd be totally amazed.

Even though we build on Hadoop 0.21.2 and Amazon EMR is only running 0.18.3, some of us think they might still work together. Have any of our users out there had success running Mahout (trunk or 0.3) on EMR?
