I am getting following exception storm topology.

I am using storm-kafka library which is deprecated. If this is the reason for above exception then let me know how to create kafka spout using storm-kafka-client library and pass custom scheme to it.
Thanks.
Could you try to also put the org.apache.kafka:kafka-clients
artifact in your dependencies, in the same version as kafka_2.11
?
Regarding how to use storm-kafka-client, there's documentation at the Storm page at https://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-kafka-client.html and examples at https://github.com/apache/storm/blob/master/examples/storm-kafka-client-examples/src/main/java/org/apache/storm/kafka/spout/KafkaSpoutTopologyMainNamedTopics.java
Specifically what you want is the RecordTranslator
.
ByTopicRecordTranslator<String, String> trans = new ByTopicRecordTranslator<>(
(r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
new Fields("topic", "partition", "offset", "key", "value"), TOPIC_0_1_STREAM);
trans.forTopic(TOPIC_2,
(r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
new Fields("topic", "partition", "offset", "key", "value"), TOPIC_2_STREAM);
return KafkaSpoutConfig.builder(bootstrapServers, new String[]{TOPIC_0, TOPIC_1, TOPIC_2})
.setProp(ConsumerConfig.GROUP_ID_CONFIG, "kafkaSpoutTestGroup")
.setRetry(getRetryService())
.setRecordTranslator(trans)
.setOffsetCommitPeriodMs(10_000)
.setFirstPollOffsetStrategy(EARLIEST)
.setMaxUncommittedOffsets(250)
.build();
This one for example will output the topic, partition, offset, key and value from each record in the fields listed, and will emit tuples from TOPIC_2 to a different stream from the other subscribed topics. If you don't need different schemes for different topics, you can use SimpleRecordTranslator
instead.
