    I am currently trying to run the Hello Samza example (http://samza.apache.org/startup/hello-samza/0.9/) and unfortunately when I try to run a Samza job I get the following exception: *Command* {code} deploy/samza/bin/run-job.sh --config-factory=org.apache.samza.config.factories.PropertiesConfigFactory --config-path=file://$PWD/deploy/samza/config/wikipedia-feed.properties {code} *Exception* {code} ...
