我尝试在azure的hdinsight sparkrunner上运行一个beam管道。我首先尝试了一个基于spark2.3.0/hadoop2.7（hdi3.6）和2.3.1/hadoop3.0（hdi4.0预览版）的集群。我尝试使用ApacheBeam2.2.0和Next2.10.0-snapshot。
spark submit命令是（对于beam 2.10.0）：

JARS="wasbs:///dependency/hadoop-azure-3.1.1.3.0.2.0-50.jar,wasbs:///dependency/azure-storage-7.0.0.jar,wasbs:///dependency/beam-model-fn-execution-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-model-job-management-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-model-pipeline-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-runners-core-construction-java-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-runners-core-java-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-runners-direct-java-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-runners-spark-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-sdks-java-core-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-sdks-java-fn-execution-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-sdks-java-io-hadoop-file-system-2.10.0-SNAPSHOT.jar,wasbs:///dependency/beam-vendor-grpc-1_13_1-0.1.jar"

spark-submit --conf spark.yarn.maxAppAttempts=1 --deploy-mode cluster --master yarn --jars $JARS --class example.MinimalWordCountJava8 wasbs:///mavenproject1-1.0-SNAPSHOT.jar --runner=SparkRunner

（最初，没有给jars提供hadoopazure和azure存储jar，但这没有任何区别）。
这个 main() 看起来像这样：

public static void main(String[] args) {

    JavaSparkContext ct = new JavaSparkContext();
    Configuration config = ct.hadoopConfiguration();

    config.set("fs.wasbs.impl", "org.apache.hadoop.fs.azure.NativeAzureFileSystem");
    config.set("fs.wasb.impl",  "org.apache.hadoop.fs.azure.NativeAzureFileSystem");
    config.set("fs.AbstractFileSystem.wasb.impl", "org.apache.hadoop.fs.azure.Wasb");
    config.set("fs.AbstractFileSystem.wasb.impl", "org.apache.hadoop.fs.azure.Wasbs");
    config.set("fs.azure", "org.apache.hadoop.fs.azure.NativeAzureFileSystem");
    config.set("fs.azure.account.key." + account + ".blob.core.windows.net", key);
    config.set("fs.defaultFS", "wasb://" + container + "@" + account + ".blob.core.windows.net");

    System.out.println("### hello.txt content:");
    JavaRDD<String> content = ct.textFile("wasbs:///hello.txt");
    System.out.println(content.toString());

    System.out.println("### MinimalWordCountJava8");

    PipelineOptions options = PipelineOptionsFactory.create();
    SparkContextOptions sparkContextOptions = options.as(SparkContextOptions.class);
    sparkContextOptions.setUsesProvidedSparkContext(true);
    sparkContextOptions.setProvidedSparkContext(ct);
    sparkContextOptions.setRunner(SparkRunner.class);

    Pipeline p = Pipeline.create(sparkContextOptions);

    p.apply(TextIO.read().from("hello.txt"))
     .apply(FlatMapElements
         .into(TypeDescriptors.strings())
         .via((String word) -> Arrays.asList(word.split("[^\\p{L}]+"))))
     .apply(Filter.by((String word) -> !word.isEmpty()))
     .apply(Count.<String>perElement())
     .apply(MapElements
         .into(TypeDescriptors.strings())
         .via((KV<String, Long> wordCount) -> wordCount.getKey() + ": " + wordCount.getValue()))
     // CHANGE 3/3: The Google Cloud Storage path is required for outputting the results to.
     .apply(TextIO.write().to("output"));

    p.run().waitUntilFinish();

调用时失败 Pipeline.create(options); 对于此异常跟踪：

提交工程（the submit works） wasps:// 是公认的）和阅读的小 wasps:///hello.txt 不会失败。这些案例表明 wasps:// 在那之前一切都很好。
这是早期内梁，它似乎失败了。
因此我通过了考试 JavaSparkContext 与 PipelineOptions （使用其他so问题/答案建议的动态hadoop配置）。但这对我来说没什么不同。
有谁能指导如何绕过这个问题？

从快速挖掘代码和bug跟踪器来看，从hadoop3.2.0（代码，jira）开始，azure似乎作为hadoop文件系统得到了支持。当前梁固定到版本2.7.3。这就解释了梁的失效 HadoopFilesystem .
可能是这样的 spark-submit 成功是因为 wasbs:// 通过与hadoop库不同的机制或使用捆绑的更新版本的hadoop来支持。
