Oh I see, you want to send to different topics. Well, then you have to give
some dummy value to the topic property on the operator.

Siyuan,
So for the output operator, we have specified it as a part of our logic
itself.
public class KafkaSinglePortExactlyOnceOutputOperator extends
AbstractKafkaOutputOperator {
private static final Logger LOG =
LoggerFactory.getLogger(KafkaSinglePortExactlyOnceOutputOperator.class);
Jaspal,
I think you miss the kafkaOut :)

After making the change, we are getting the below error while application
launch:
*An error occurred trying to launch the application. Server message:
javax.validation.ConstraintViolationException: Operator kafkaOut violates
constraints
Should we use malhar-library version 3.5 then ?
Thanks!!

Hey Jaspal,
Did you add any code to existing KafkaSinglePortExactlyOnceOutputOperator from
malhar? If so please make sure the producer you use here
is org.apache.kafka.clients.producer.KafkaProducer instead of
kafka.javaapi.producer.Producer. That is old api and that is not supported
by MapR
Thomas,
We have added the dependency in pom.xml for lafka client API and also for
malhar kafka. Please highlight if you are specifying some other dependency
that we need to add.
org.apache.apex
malhar-kafka
${malhar.version}
org.apache.kafka
kafka-clients
Thomas,
Below is the operator implementation we are trying to run. This operator is
getting an object of tenant class from updtream operator.
public class KafkaSinglePortExactlyOnceOutputOperator extends
AbstractKafkaOutputOperator {
private static final Logger LOG =
The KafkaSinglePortExactlyOnceOutputOperator takes whatever output from
previous operator and writes to Kafka.

Hi Thomas,
I have a question, so when we are using
*KafkaSinglePortExactlyOnceOutputOperator* to write results into maprstream
topic will it be able to read messgaes from the previous operator ?
Thanks
