Kafka Input Operator questions
Hi,
I have a few quick questions around the Kafka Input Operators, to confirm that I am implementing them correctly.
1) We are using kafka version 0.8.x, and I want to confirm that the 0.8.x input operators for kafka are located in https://github.com/apache/apex-malhar/tree/master/contrib/src/main/java/com/datatorrent/contrib/kafka
2) For setting zookeeper and topic in the input operator, I see that setZookeeper and setTopic methods are both deprecated. I just want to confirm that I should not be creating a consumer instance and setting these properties in the consumer vs the operator level I am currently setting them on the operator via the properties file as shown below and I want to confirm that this is correct:
<property>
<name>dt.operator.kafkaInputOperator.prop.topic</name>
<value></value>
</property>
3) For exactly once processing, we in examples we see that we need to setIdempotentStorageManager on the on the input operator. It appears though that IdempotentStorageManager is deprecated. Is there an alternative that we can use if we are running 3.3.0 of apex engine and 3.3.1 of Malhar?

Hi Eric,
I would recommend to use the latest version of Apex Core (3.4.0) as well as the latest version of Malhar (3.4.0 as well).
My responses inline based on above versions:

Yes, this is the location for the Kafka 0.8.x compatible consumer.
2) For setting zookeeper and topic in the input operator, I see that setZookeeper and setTopic methods are both deprecated. I just want to confirm that I should not be creating a consumer instance and setting these properties in the consumer vs the operator level I am currently setting them on the operator via the properties file as shown below and I want to confirm that this is correct:
<property>
<name>dt.operator.kafkaInputOperator.prop.topic</name>
<value></value>
</property>
Please use the setters of the consumer instead. Path would be dt.operator.kafkaInputOperator.prop.consumer.topic
3) For exactly once processing, we in examples we see that we need to setIdempotentStorageManager on the on the input operator. It appears though that IdempotentStorageManager is deprecated. Is there an alternative that we can use if we are running 3.3.0 of apex engine and 3.3.1 of Malhar?
The replacement is WindowDataManager and the operator was updated in v3.4.0 to reflect this.
