custom value.deserializer for storm-kafka-client-1.1.1?
Hello,
I am trying to use a custom ValueDeserializer when consuming from kafka, I
tried the following
--snip--
KafkaSpoutConfig kafkaSpoutConfig = KafkaSpoutConfig
.builder(property.getKafka_consumer_bootstrap_servers(), topics)
.setFirstPollOffsetStrategy(KafkaSpoutConfig.FirstPollOffsetStrategy.EARLIEST)
.setGroupId(property.getKafka_consumer_groupid())
.setProp(ConsumerConfig.CLIENT_ID_CONFIG, "StormKafkaConsumer")
.setProp(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG,
"EmailObjectDeserializer")
.build();
--snip--
It didn't take, In the logs I still see spout executor instantiated with
default "StringDeserializer" class.
--snip--

Please check that you are implementing SerializableDeserializer<T> for some
type T and not the raw type.

Thanks Stig,
So I tried using

and the EmailObjectDeserializer class is implementing the interface
org.apache.storm.kafka.spout.SerializableDeserializer
>> public class EmailObjectDeserializer implements SerializableDeserializer
{...}
I see the following compilation error..

I tried implementing the org.apache.kafka.common.serialization.Deserializer
class too and got the same error..
Thanks for your help. /Manish

Posted by Stig Rohde Døssing <sr...@apache.org>.
Hi Manish,
The setProp method will not work for setting deserializers until Storm
1.2.0. For 1.1.1 you will need to use setKey/setValue to set a different
deserializer.
e.g.
KafkaSpoutConfig kafkaSpoutConfig = KafkaSpoutConfig
.builder(property.getKafka_consumer_bootstrap_servers(), topics)
.setValue(TestDeserializer.class)
.build()
Also when you upgrade to 1.2.0 please note that you can either do
.setProp(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG,
EmailObjectDeserializer.class)
or
.setProp(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG,
"com.example.EmailObjectDeserializer")
that is, you need to use the fully qualified class name of the deserializer
class if you're setting it as a string.
