Hi Josh, Thanks for the help.
The class should be on the path on all nodes. Here's what I did: 1) I built a jar from my scala code. 2) I copied that jar to a location on all nodes in my cluster (/usr/local/spark) 3) I edited bin/compute-classpath.sh to add my jar to the class path. 4) I repeated the process with the avro mapreduce jar to provide AvroKey. I doubt this is the best way to set the classpath but it seems to work.
