Can you let me know how is you pom.xml looks like ? In the consumer pom, Kafka and Spark versions are provided. You need to explicitly mention the Kafka and Spark version in you pom.xml.
or if you are trying the example directly , you need to modify the pom.xml of the consumer and remove provided tag and also update the versions of Kafka and Spark what you are using .

Thanks, I'll try it this evening

dibbhatt commented

Are you still having same issue ?

jekey commented

I got the error too....
it's my sbt file

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.4.1"
libraryDependencies += "org.apache.spark" % "spark-streaming_2.10" % "1.4.1"
libraryDependencies += "org.codehaus.jackson" % "jackson-mapper-asl" % "1.9.13"
libraryDependencies += "dibbhatt" % "kafka-spark-consumer" % "1.0.6"

oh, I fix it ,
by add libraryDependencies += "org.apache.spark" % "spark-streaming-kafka_2.10" % "1.4.1"

dibbhatt commented

Ok cool

dibbhatt commented

closing this as this is the related to your pom/sbt missing dependency .
