Apache Beam Spark Runner 问题

Question

我们正在尝试使用以下命令通过 YARN 提交 Spark 作业：

spark-submit --conf spark.yarn.stagingDir=/path/to/stage  --verbose --class com.my.class --jars /path/to/jar1,path/to/jar2 /path/to/main/jar/application.jar

该应用程序正在 YARN 调度程序中填充，但它似乎从未启动 Application Master 容器。轨迹是：

17/12/04 11:21:32 WARN Client: Neither spark.yarn.jars nor spark.yarn.archive is set, falling back to uploading libraries under SPARK_HOME.
17/12/04 11:27:16 ERROR SparkContext: Error initializing SparkContext.

我们能够运行示例 Spark Pi 作业无误地完成。

版本：

$ spark-submit --version
Welcome to
      ____              __
     / __/__  ___ _____/ /__
    _\ \/ _ \/ _ `/ __/  '_/
   /___/ .__/\_,_/_/ /_/\_\   version 2.1.0-mapr-1703
      /_/

Using Scala version 2.11.8, Java HotSpot(TM) 64-Bit Server VM, 1.8.0_101

我们认为问题可能出在我们设置管道的方式上：

    PipelineOptions options = PipelineOptionsFactory.create();
    options.setRunner(SparkRunner.class);
    Pipeline p = Pipeline.create(options);

我们运行我们的管道有：

p.run(options);

管道已运行与 DirectRunner 成功连接。

我们确保将 beam-运行ners-spark 作为 Maven 依赖项包含在内。

Answer 1

Apache Beam 目前仅支持 Apache Spark 1.6.3。我们目前使用的是 Apache Spark 2.1，因此它无法正常工作。
