Java Dataproc依赖项冲突-google api客户端

我正在构建一个用于从云存储获取加密机密的库（在Scala中，使用Java客户端）。我正在使用以下google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",

本地一切正常，但当我尝试在Dataproc中运行代码时，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)

我在图中看到，一些google库在Dataproc上可用（我使用的是图像版本为1.2.15的Spark集群）。但就我所见，GoogleAPI客户端的可传递依赖项与我在本地使用的相同（1.23.0）。那么为什么找不到这种方法呢

我应该为在Dataproc上运行设置不同的依赖项吗

编辑 最终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连接器！！），还必须向JVM注册着色类来处理gs://文件系统。 以下是适用于我的maven配置，sbt也可以实现类似的功能：

google api客户端

版本实际上是

1.20.0

原因是，它是一系列提交的一部分，包括这一部分，其总体目标是不再将可传递依赖项泄漏到作业类路径中，这正是为了避免将来的版本冲突问题，代价是每个人都必须自带包含完整api客户机依赖项的胖罐子

然而，事实证明，许多人已经开始依赖GCS连接器提供的api客户机在类路径上，因此存在一些生产工作负载，它们无法在小版本升级中经受住这样的变化；因此，升级后的GCS连接器使用1.23.0，但也对其进行了着色，使其不再出现在作业类路径中，该连接器将保留给未来的Dataproc 1.3+或2.0+版本

在您的情况下，您可以尝试使用依赖项的

1.20.0

版本（您可能还必须降级所包含的

googlecloudstorage

依赖项的版本，尽管该版本的

1.22.0

版本在假设没有重大更改的情况下仍然可以工作，因为setBatchPath实际上只在

中引入），否则您可以尝试

谢谢你的回复Dennis。我正在尽我最大的努力给google库加上阴影，但是我在Dataproc上一直遇到一个错误：

线程“main”java.lang.AbstractMethodError:MyClass$.gcp$EncryptedSecretsUser$\u setter\u$creds\u$eq（Lcomgoogleshade/api/client/googleapis/auth/oauth2/GoogleCredential；）V

。有问题的行是

val creds:GoogleCredential=GoogleCredential.getApplicationDefault

。显然，我仍然从类路径中找到一些不兼容的库。知道这是从哪里来的吗？你能告诉我要对哪些库进行着色吗？是的，我的着色规则是

ShadeRule.rename（“com.google.*.*”->>“comgoogleshade@1shade@2”）.inAll

，我验证了我正在生成的胖罐子中没有com/google路径。错误表明我的shade com.google.api被拾取：

线程“main”java.lang.AbstractMethodError中的异常：MarketMonitorETL$.gcp$EncryptedSecretsUser$\u setter\uds\u$eq（L**comgoogleshade/apishade/**client/googleapis/auth/oauth2/GoogleCredential；）V

成功实现了这一点。必须屏蔽所有google依赖项，包括gcs连接器，并将我的屏蔽类注册为文件系统提供程序。请参阅问题中的编辑。感谢您的回复Dennis。我正在尽最大努力屏蔽google库，但在Dataproc上不断出现错误：
