【问题描述】：

无法通过 spark-atlas-connector 使用 apache atlas 设置我的 spark 应用程序。

我已经克隆了 https://github.com/hortonworks-spark/spark-atlas-connector 项目并执行了 mvn 包。然后我把所有的罐子放在我的项目中，并像这样设置配置：

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

    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", "foobar")
      .option("startingOffset", "earliest")
      .load()

    df.show()

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

  }

Atlas 是通过我拉的 docker 容器启动的。 Kafka with Zookeper 是通过我拉的 docker 容器盯着看的。

这项工作在没有 spark-atlas-connector 的情况下工作，但是当我想添加一个连接器时，它会引发异常。

【解决方案1】：

System.setProperty("atlas.conf", "") 是 OP 指出的正确解决方案。 SAC 使用 ApplicationProperties.java。

具体来说，它使用 ApplicationProperties.get。源代码在这里： https://github.com/apache/atlas/blob/master/intg/src/main/java/org/apache/atlas/ApplicationProperties.java#L118

您可以看到变量 ATLAS_CONFIGURATION_DIRECTORY_PROPERTY 设置为“atlas.conf”： https://github.com/apache/atlas/blob/master/intg/src/main/java/org/apache/atlas/ApplicationProperties.java#L43

【解决方案2】：

我相信您已经忘记了设置文档中的另一个步骤。您遇到的错误源于

Caused by: com.hortonworks.spark.atlas.shade.org.apache.commons.configuration.ConfigurationException: Cannot locate configuration source null

并在您发布的 github 存储库中引用他们的 README 文件：

还要确保 atlas 配置文件 atlas-application.properties 在驱动程序的类路径中。例如，将此文件放入<SPARK_HOME>/conf。

【讨论】：

我在 Intelijj idea 工作，并在那里开始工作（没有控制台）。我在里面创建了带有文件夹 conf 的环境 SPARK_HOME 并放在那里 atlas-application.properties 但无论如何都有问题
天啊！ atlas-application.properties 路径应该在属性中。我的意思是在你的工作中它应该看起来像这样 System.setProperty("atlas.conf", "")。

【解决方案3】：

请参阅官方 spark-atlas-connector github 页面。 atlas-application.properties 文件应该是可访问的。

还要确保 atlas 配置文件 atlas-application.properties 位于驱动程序的类路径中。例如，将此文件放入 /conf。如果您使用集群模式，请同时使用 --files atlas-application.properties 将此 conf 文件发送到远程驱动器。

【讨论】：

【解决方案4】：

以下应该可以解决问题。请注意 --files 和 --driver-class-path 选项是将此配置文件放置在 CLASSPATH 上所必需的，因此可用于 Atlas Client 类。

此外，spark-shell 使用相对于 Spark Atlas 连接器的路径，因此请进行相应更改。

$SPARK_HOME/bin/spark-shell \
  --jars spark-atlas-connector-assembly/target/spark-atlas-connector-assembly-0.1.0-SNAPSHOT.jar \
  --conf spark.extraListeners=com.hortonworks.spark.atlas.SparkAtlasEventTracker \
  --conf spark.sql.queryExecutionListeners=com.hortonworks.spark.atlas.SparkAtlasEventTracker \
  --conf spark.sql.streaming.streamingQueryListeners=com.hortonworks.spark.atlas.SparkAtlasStreamingQueryEventTracker \
  --files spark-atlas-connector/src/test/resources/atlas-application.properties \
  --driver-class-path spark-atlas-connector/src/test/resources
