Ah! Perfect. I'll poke through the docs and hope for a smooth transition. Thanks!

The setup code is completely different. The code you posted is still using the storm-kafka classes (e.g. old SpoutConfig instead of new KafkaSpoutConfig), so you're still on the old spout. I'm a little surprised that code even compiled for you before, since the sbt you posted doesn't list storm-kafka anymore. There's documentation for the new spout at https://storm.apache.org/releases/1.1.1/storm-kafka-client.html, and some example code at https://github.com/apache/storm/blob/master/examples/storm-kafka-client-examples/src/main/java/org/apache/storm/kafka/spout/KafkaSpoutTopologyMainNamedTopics.java. 2018-01-13 21:15 GMT+01:00 M. Aaron Bossert <maboss...@gmail.com<mailto:maboss...@gmail.com>>: Stig, This project is still in a POC status, so I can wipe and restart anything...no big deal. Thanks! So, I am now seeing some build errors when I try to run my assembly. Is there a different method for setting up the KafkaSpout?

Do you need offsets migrated, or is it fine if the consumers start from scratch? I don't know whether HDP has special requirements but here's the general how-to for setting up storm-kafka-client: The storm-kafka-client library should work with any Kafka version 0.10.0.0 and above. You should use the latest version of storm-kafka-client, which is currently 1.1.1. If you want a decent number of extra fixes, you might consider building version 1.2.0 yourself from https://github.com/apache/storm/tree/1.x-branch/external/storm-kafka-client, we are hoping to release this version before too long. Once you've declared a dependency on storm-kafka-client, you should also add a dependency on org.apache.kafka:kafka-clients, in the version that matches your Kafka broker version. Looking at your sbt you should not need org.apache.kafka:kafka on the classpath. I think your zookeeper, log4j and slf4j-log4j12 exclusions on storm-kafka-client are unnecessary as well. I don't believe those dependencies are part of the storm-kafka-client dependency tree. In case making those changes doesn't solve it, could you post a bit more of the stack trace you get? 2018-01-13 20:23 GMT+01:00 M. Aaron Bossert <maboss...@gmail.com<mailto:maboss...@gmail.com>>: All, I have resurrected some old code that includes a Kafka Producer class as well as a storm topology that includes a Kafka Spout to ingest the messages coming from the aforementioned producer. I was using the storm-kafka library with Scala 2.11, but when I changed to the newer code base, which is using Scala 2.12, I found that the older library wouldn't work...thus I wanted to switch to the new storm-kafka-client, but am not sure what version I should be using. here is my build.sbt file, as well as the error messages I am seeing when the Spout actually runs (my favorite assistant, Google, tells me it is due to a version mismatch between Storm and Kafka).
