我正在构建一个库，用于从云存储中获取加密的秘密（在 Scala 中，使用 Java 客户端）。我正在使用以下谷歌库：

"com.google.apis"  % "google-api-services-cloudkms" % "v1-rev26-1.23.0" exclude("com.google.guava", "guava-jdk5"),
"com.google.cloud" % "google-cloud-storage"         % "1.14.0",

在本地一切正常，但是当我尝试在 Dataproc 中运行我的代码时，出现以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.api.client.googleapis.services.json.AbstractGoogleJsonClient$Builder.setBatchPath(Ljava/lang/String;)Lcom/google/api/client/googleapis/services/AbstractGoogleClient$Builder;
    at com.google.api.services.cloudkms.v1.CloudKMS$Builder.setBatchPath(CloudKMS.java:4250)
    at com.google.api.services.cloudkms.v1.CloudKMS$Builder.<init>(CloudKMS.java:4229)
    at gcp.encryption.EncryptedSecretsUser$class.clients(EncryptedSecretsUser.scala:111)
    at gcp.encryption.EncryptedSecretsUser$class.getEncryptedSecrets(EncryptedSecretsUser.scala:62)

我的代码中的违规行是：

val kms: CloudKMS = new CloudKMS.Builder(credential.getTransport,
      credential.getJsonFactory,
      credential)
      .setApplicationName("Encrypted Secrets User")
      .build()

我在文档中看到 Dataproc 上提供了一些谷歌库（我使用的是带有映像版本 1.2.15 的 Spark 集群）。但据我所见，google-api-client 的传递依赖与我在本地使用的相同（1.23.0）。那怎么找不到方法呢？

为了在 Dataproc 上运行，我是否应该设置不同的依赖项？

最后设法在另一个项目中解决了这个问题。事实证明，除了着色所有 google 依赖项（包括 gcs-connector ！！），您还必须向 JVM 注册您的着色类以处理 gs:// 文件系统。下面是适用于我的 maven 配置，可以使用 sbt 实现类似的功能：

并添加一个名为org.apache.hadoop.fs.FileSystemunder的文件path/to/your-project/src/main/resources/META-INF/services，其中包含您的着色类的名称，例如：

# WORKAROUND FOR DEPENDENCY CONFLICTS ON DATAPROC
#
# Use the shaded class as a provider for the gs:// file system
#

com.shaded.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem

（注意这个文件是从gcs-connector父 POM 的库中过滤出来的）

可能不是很明显，但google-api-client最新稳定的 GCS 连接器中的版本实际上是1.20.0.

原因是这是将 api 客户端版本向前滚动到 1.23.0 的提交，它是一系列提交的一部分，包括此依赖项着色提交，其总体目标是不再将传递依赖项泄漏到作业类路径中毕竟，正是为了避免将来出现版本冲突问题，代价是每个人都必须自己携带包含完整 api 客户端依赖项的 fat jar。

然而，事实证明，许多人已经成长为依赖 GCS 连接器提供的 api 客户端在类路径上，因此存在生产工作负载，在小版本升级中无法承受这样的变化；因此，升级后的 GCS 连接器使用 1.23.0，但也会对其进行遮蔽，以便它不会再出现在作业类路径中，为未来的 Dataproc 1.3+ 或 2.0+ 版本保留。

在您的情况下，您可以尝试使用1.20.0您的依赖项的版本（您可能还必须降级google-cloud-storage您包含的依赖项的1.22.0版本，尽管假设没有重大更改，该版本可能仍然有效，因为 setBatchPath 确实仅在 中引入1.23.0），或者，您可以尝试使用 sbt-assembly 隐藏所有自己的依赖项。

我们可以验证setBatchPath仅在1.23.0：

$ javap -cp google-api-client-1.22.0.jar com.google.api.client.googleapis.services.AbstractGoogleClient.Builder | grep set
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setRootUrl(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setServicePath(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setGoogleClientRequestInitializer(com.google.api.client.googleapis.services.GoogleClientRequestInitializer);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setHttpRequestInitializer(com.google.api.client.http.HttpRequestInitializer);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setApplicationName(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressPatternChecks(boolean);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressRequiredParameterChecks(boolean);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressAllChecks(boolean);

$ javap -cp google-api-client-1.23.0.jar com.google.api.client.googleapis.services.AbstractGoogleClient.Builder | grep set
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setRootUrl(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setServicePath(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setBatchPath(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setGoogleClientRequestInitializer(com.google.api.client.googleapis.services.GoogleClientRequestInitializer);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setHttpRequestInitializer(com.google.api.client.http.HttpRequestInitializer);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setApplicationName(java.lang.String);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressPatternChecks(boolean);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressRequiredParameterChecks(boolean);
  public com.google.api.client.googleapis.services.AbstractGoogleClient$Builder setSuppressAllChecks(boolean);
