Hadoop classpath psudo-distributed mode

I'm running some simple tests of Hadoop locally in psudo-distributed mode. But the reducer is giving me a ClassNotFoundException.

I've got the HADOOP_CLASSPATH set as such:

export HADOOP_CLASSPATH=/home/davidparks21/hadoop/FruggMapreduceJobs.jar:/home/davidparks21/hadoop/hadoop-1.0.3/lib/*

And I've got all of these classes in $HADOOP_INSTALL/lib/

What am I missing?

I just needed to restart mapreduce (stop-mapred.sh/start-mapred.sh) so that it loaded and distrubted my new jars appropriately.
