That was it, and some more configurations that were missing:
task.class=samzafroga.job1
job.factory.class=org.apache.samza.job.local.ThreadJobFactory
job.name=samzafroga.job1
systems.kafka.producer.bootstrap.servers=broker01:9092
Now I am getting this exception:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/jetty/server/Handler

org.apache.samza.coordinator.JobCoordinator$.apply(JobCoordinator.scala:56)

What I don’t understand is that the jetty jar is included in the job. Could it
be a version problem? I am using jetty-util-6.1.26.jar.
Thanks,
Jordi

Hi Jordi,
I think you need to add the "job.factory.class" property.
http://samza.apache.org/learn/documentation/0.8/jobs/configuration-table.html
#An example
job.factory.class=org.apache.samza.job.local.ThreadJobFactory
Cheers,
Roger
