Hello Samza Example Issues

[ma...@yahoo.com.au]

I am currently trying to run the Hello Samza example at (http://samza.apache.org/startup/hello-samza/0.9/) and unfortunately when I try to run a Samza job I get the following error: 


deploy/samza/bin/run-job.sh --config-factory=org.apache.samza.config.factories.PropertiesConfigFactory --config-path=file://$PWD/deploy/samza/config/wikipedia-feed.properties

If I edit vim deploy/samza/bin/run-class.sh and manually add the scala-library.jar to the CLASSPATH value, this error disappears, though the Hadoop job will fail with a similarish exception.
