Hello,
I am trying to run my first job (publish what receives) in Samza and I think
that all the dependencies where added by configuring the Maven repositories
(solved in a recent question to the list). I am getting another exception on
the Job runner:

Exception in thread "main" org.apache.samza.SamzaException: no job factory

at org.apache.samza.job.JobRunner$.main(JobRunner.scala:37)
at org.apache.samza.job.JobRunner.main(JobRunner.scala)
My properties file is this:
task.class=samzafroga.job1
systems.kafka.samza.factory=org.apache.samza.system.kafka.KafkaSystemFactory
systems.kafka.consumer.zookeeper.connect=acio-broker01:2181,acio-broker02:2181
task.inputs=kafka.frogain
serializers.registry.json.class=org.apache.samza.serializers.JsonSerdeFactory
systems.kafka.streams.frogain.samza.msg.serde=json
This is the code job code:
package samzafroga;
import org.apache.samza.config.Config;
import org.apache.samza.system.IncomingMessageEnvelope;
import org.apache.samza.system.OutgoingMessageEnvelope;
import org.apache.samza.system.SystemStream;
import org.apache.samza.task.MessageCollector;
import org.apache.samza.task.StreamTask;
import org.apache.samza.task.TaskContext;
import org.apache.samza.task.TaskCoordinator;
public class job1 implements StreamTask {
private final SystemStream OUTPUT_STREAM = new
SystemStream("kafka", "beste");
public void process(IncomingMessageEnvelope envelope,
MessageCollector collector, TaskCoordinator coordinator)
{
String msg = (String)envelope.getMessage();
String outmsg = msg;
collector.send(new
OutgoingMessageEnvelope(OUTPUT_STREAM, outmsg));
}
}
I have been trying to read the code in the file JobRunner.scala, that
apparently is the one generation the exception and as I understand is having a
problem . I am not really sure if the problem is with the task.class definition
or I still have something missing in the system.
Thanks in advance,
Jordi
