我正在构建一个库,用于从云存储中获取加密机密(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)
我的代码中有问题的一行是:
val kms: CloudKMS = new CloudKMS.Builder(credential.getTransport,
credential.getJsonFactory,
credential)
.setApplicationName("Encrypted Secrets User")
.build()
我在
documentation
Dataproc上有一些google库(我使用的是一个Spark集群,图像版本为1.2.15)。但就我所见,google api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,为什么找不到该方法呢?
我是否应该为在Dataproc上运行设置不同的依赖项?
编辑
最终在另一个项目中解决了这个问题。事实证明,除了隐藏所有google依赖项(包括gcs连接器!!),您还必须向JVM注册着色类来处理gs://file系统。
以下是适用于我的maven配置,sbt也可以实现类似的功能:

,包含着色类的名称,例如:

# Use the shaded class as a provider for the gs:// file system
#
com.shaded.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem
