Yes, there is no code overlap between storm-kafka and storm-kafka-client. 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.

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?

and here is the relevant part of my topology:

// Set up the Kafka Spout
val zkHosts: BrokerHosts = new ZkHosts("r7u07:2181,r7u08:2181,r7u09:2181")
val pcapKafkaTopic: String = "packets"
val pcapZkRoot: String = "/packets"
val pcapClientId: String = "PcapKafkaSpout"

val pcapKafkaConf: SpoutConfig = new SpoutConfig(zkHosts,pcapKafkaTopic,pcapZkRoot,pcapClientId)
pcapKafkaConf.ignoreZkOffsets = true
pcapKafkaConf.useStartOffsetTimeIfOffsetOutOfRange = true
pcapKafkaConf.startOffsetTime = kafka.api.OffsetRequest.EarliestTime
pcapKafkaConf.outputStreamId = "packets"
pcapKafkaConf.scheme = new SchemeAsMultiScheme(new PcapRecordKafkaScheme)

val pcapKafkaSpout = new KafkaSpout(pcapKafkaConf)

// Generates list of PCAP files to process, periodically scanning a magic directory for new files
topologyBuilder.setSpout("pcapKafkaSpout", pcapKafkaSpout,PcapFileSpoutWorkers)
.setNumTasks(PcapFileSpoutTasks)
.setMemoryLoad(16 * 1024)

Hi Aaron,

Please note that the position of your storm-kafka consumers won't be migrated, so the new storm-kafka-client spout will start over on the topics you subscribe to. 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?

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).  I am using HDP 2.6.2, for whatever that is worth...
