我试图从最早的偏移量到最新的偏移量查询kafka，然后将其写入hadoop。
但问题是我越来越 java.lang.AbstractMethodError 即使我没有在代码中调用任何抽象方法。
这是我试图查询Kafka的代码

import org.apache.log4j.Logger
import org.apache.spark.SparkConf
import org.apache.spark.sql.{SaveMode, SparkSession}
import org.json.JSONObject

case class Metric(timestamp: String, hostName: String)

object KafkaMetrcs {

  val logger = Logger.getLogger(this.getClass.getName)

  def getSparkConf(appName: String): SparkConf = {
    new SparkConf().setAppName(appName)
    //.setMaster("local[*]")

  }

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

    val sparkConf = new SparkConf()
    implicit val sparkSession = SparkSession.builder().config(sparkConf).getOrCreate()
    sparkSession.sparkContext.setLogLevel("INFO")

    import sparkSession.implicits._

    val bootstrapServers = "kafka-vip.com:1234"
    val outputLocation = "hdfs://kafka_metrics/output"

    val inputds = sparkSession.read.format("kafka")
      .option("kafka.bootstrap.servers", bootstrapServers)
      .option("subscribe", "fpti.platform.metrics")
      .option("startingOffsets", "earliest")
      .option("endingOffsets", "latest")
      .option("fetchOffset.numRetries", 5)
      .option("failOnDataLoss", "false")
      .load()
      .selectExpr("CAST(value AS STRING)")
      .as[String]

    val outputds = inputds.map(record => extractValuesFromRecord(record))
    outputds.write.mode(SaveMode.Overwrite).json(outputLocation)

  }

  def extractValuesFromRecord(record: String): Metric = {
    val jsonRecord = new JSONObject(record)
    val timestamp = jsonRecord.getString("timestamp")
    val hostName = jsonRecord.getString("hostName")
    Metric(timestamp, hostName)
  }

}

它是非常简洁的代码块，任何地方都没有抽象函数。但这是混乱的，因为我得到的错误。感谢您的帮助。提前多谢了
