Question on KafkaInputOperator - with kafka 0.8.2.1

["Martin, Eric" <Er...@capitalone.com>]

Hi all,

I am using the 0.8.x version of the Kafka Input Operators. When using these operators, I am able to run the application fine while using kafka version 0.8.1.1. However, if I use version 0.8.2.x, I am not able to run the application even though the kafka cluster that I am connecting is running on 0.8.2.1.

The exception that I am getting is:
java.lang.NoSuchMethodError: kafka.cluster.Broker.getConnectionString()Ljava/lang/String;

at com.datatorrent.contrib.kafka.KafkaMetadataUtil.getBrokers(KafkaMetadataUtil.java:114)
at com.datatorrent.contrib.kafka.KafkaConsumer.initBrokers(KafkaConsumer.java:131)
at com.datatorrent.contrib.kafka.AbstractKafkaInputOperator.definePartitions(AbstractKafkaInputOperator.java:488)

It would appear that the getConnectionString() method is not supported in kafka 0.8.2.x. Using 0.8.1.x is not a huge issue for most things, but I am looking to keep track of offsets in topics and this only appears to be available with kafka 0.8.2.x.

Is there any known work around for this issue, so that I can use 0.8.2.x in the application?

Thanks,
Eric

Hi Eric,

You need to use the 0.8.1 version of the client library. It can talk to the
0.8.2 cluster.

Thanks,
Thomas
