启动期间Spark-Atlas-Connector NullPointerException

Question

我正在尝试开始我为测试与Atlas的集成火花所做的工作。

这是一个简单的工作，它从一个主题读取并写入另一个主题。

  val sparkConf = new SparkConf()
      .setAppName("atlas-test")
      .setMaster("local[2]")
      .set("spark.extraListeners", "com.hortonworks.spark.atlas.SparkAtlasEventTracker")
      .set("spark.sql.queryExecutionListeners", "com.hortonworks.spark.atlas.SparkAtlasEventTracker")
      .set("spark.sql.streaming.streamingQueryListeners", "com.hortonworks.spark.atlas.SparkAtlasStreamingQueryEventTracker")


    val spark = SparkSession.builder()
      .config(sparkConf)
      .enableHiveSupport()
      .getOrCreate()

    import spark.implicits._


    val df = spark.read.format("kafka")
      .option("kafka.bootstrap.servers", BROKER_SERVERS)
      .option("subscribe", "foobar2")
      .option("startingOffset", "earliest")
      .option("kafka.atlas.cluster.name", clusterName)
      .load()

    println("---------------------------------------------")

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

    dfs.show()
    println("---------------------------------------------")

    df.write
      .format("kafka")
      .option("kafka.bootstrap.servers", BROKER_SERVERS)
      .option("topic", "foobar-out")
      .option("kafka.atlas.cluster.name", clusterName)
      .save()

一切似乎都是可以理解的。因此，我尝试在我的IDE（Intellij）中运行该作业，几乎每次我遇到此异常时

我正在将Spark 2.4.0与Scala 2.11一起使用

我对结果有些误解。老实说，在我的地图集（本地计算机）中完成这项工作后，我会无法理解吗？因为有时作业运行成功，但Atlas中什么也没出现。
