KafkaUtils class not found in Spark streaming

Question

I have just began with Spark Streaming and I am trying to build a sample application that counts words from a Kafka stream. Although it compiles with sbt package

Answer 1

Following build.sbt worked for me. It requires you to also put the sbt-assembly plugin in a file under the projects/ directory.

build.sbt

name := "NetworkStreaming" // https://github.com/sbt/sbt-assembly/blob/master/Migration.md#upgrading-with-bare-buildsbt

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-streaming_2.10" % "1.4.1",
  "org.apache.spark" % "spark-streaming-kafka_2.10" % "1.4.1",         // kafka
  "org.apache.hbase" % "hbase" % "0.92.1",
  "org.apache.hadoop" % "hadoop-core" % "1.0.2",
  "org.apache.spark" % "spark-mllib_2.10" % "1.3.0"
)

mergeStrategy in assembly := {
  case m if m.toLowerCase.endsWith("manifest.mf")          => MergeStrategy.discard
  case m if m.toLowerCase.matches("meta-inf.*\\.sf$")      => MergeStrategy.discard
  case "log4j.properties"                                  => MergeStrategy.discard
  case m if m.toLowerCase.startsWith("meta-inf/services/") => MergeStrategy.filterDistinctLines
  case "reference.conf"                                    => MergeStrategy.concat
  case _                                                   => MergeStrategy.first
}

project/plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.1")
