scala - Spark 和 Kafka 集成 - 无法实例化 KafkaSourceProvider

问题描述

我正在研究 Kafka 和 Spark 的集成项目，我正在尝试使用 Spark 2.4.5、Scala 2.12.11 和 Kafka 2.5.0 阅读 Kafka 主题。

我的 sbt 文件是：

name := "Test"
version := "1.0"
scalaVersion := "2.12.11"
libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-sql_2.12" % "2.4.5",
  "org.apache.spark" % "spark-sql-kafka-0-10_2.12" % "2.4.5",
  "org.apache.spark" % "spark-streaming-kafka-0-10-assembly_2.12" % "2.4.5",
  "org.apache.kafka" % "kafka-clients" % "2.5.0"
)

我的代码是：

object Test{
def main(args: Array[String]) = {

    import org.apache.spark.sql.SparkSession

    val spark = SparkSession
              .builder()
              .appName("SparkTest")
              .master("local[*]")
              .getOrCreate()

    import spark.implicits._

    val df = spark.readStream
             .format("kafka")
             .option("kafka.bootstrap.servers", "localhost:9092")
             .option("subscribe", "test")
             .option("startingOffsets", "earliest")
             .load()

    df.selectExpr("CAST(key AS STRING)", "CAST(value AS STRING)")
           .as[(String, String)]

    df.printSchema()
}}

在 Kafka 上创建主题后，启动 zookeeper 和 Kafka 本身，当我启动代码时：

./spark-submit --packages org.apache.spark:spark-sql-kafka-0-10_2.12:2.4.5 --class Test /home/luca/Projects/Test/target/scala-2.12/test_2.12-1.0.jar

我遇到以下错误：

有人可以帮我解决这个问题吗？
