Google Cloud Dataflow error: "The Application Default Credentials are not available"
Google Cloud Dataflow error: "The Application Default Credentials are not available"
我们有一个 Google Cloud Dataflow 作业，它写入 Bigtable（通过 HBase API）。不幸的是，由于以下原因，它失败了：
java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information. at com.google.bigtable.repackaged.com.google.auth.oauth2.DefaultCredentialsProvider.getDefaultCredentials(DefaultCredentialsProvider.java:74) at com.google.bigtable.repackaged.com.google.auth.oauth2.GoogleCredentials.getApplicationDefault(GoogleCredentials.java:54) at com.google.bigtable.repackaged.com.google.cloud.config.CredentialFactory.getApplicationDefaultCredential(CredentialFactory.java:181) at com.google.bigtable.repackaged.com.google.cloud.config.CredentialFactory.getCredentials(CredentialFactory.java:100) at com.google.bigtable.repackaged.com.google.cloud.grpc.io.CredentialInterceptorCache.getCredentialsInterceptor(CredentialInterceptorCache.java:85) at com.google.bigtable.repackaged.com.google.cloud.grpc.BigtableSession.<init>(BigtableSession.java:257) at org.apache.hadoop.hbase.client.AbstractBigtableConnection.<init>(AbstractBigtableConnection.java:123) at org.apache.hadoop.hbase.client.AbstractBigtableConnection.<init>(AbstractBigtableConnection.java:91) at com.google.cloud.bigtable.hbase1_0.BigtableConnection.<init>(BigtableConnection.java:33) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.<init>(CloudBigtableConnectionPool.java:72) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.createConnection(CloudBigtableConnectionPool.java:72) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.getConnection(CloudBigtableConnectionPool.java:64) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.getConnection(CloudBigtableConnectionPool.java:57) at com.google.cloud.bigtable.dataflow.AbstractCloudBigtableTableDoFn.getConnection(AbstractCloudBigtableTableDoFn.java:96) at com.google.cloud.bigtable.dataflow.CloudBigtableIO$CloudBigtableSingleTableBufferedWriteFn.getBufferedMutator(CloudBigtableIO.java:836) at com.google.cloud.bigtable.dataflow.CloudBigtableIO$CloudBigtableSingleTableBufferedWriteFn.processElement(CloudBigtableIO.java:861)
这没有什么意义，因为该作业已经 运行 在 Cloud Dataflow service/VMs 上 service/VMs。

我们正在使用 bigtable-hbase-dataflow 版本 0.3.0，我们想使用 HBase API。
我认为这是一个已知问题，GCE 实例在启动期间很少无法获得默认凭据。
我们一直在努力修复，应该是下一个版本 (1.6.0) 的一部分，该版本应该很快就会发布。与此同时，我们建议重新提交应该有效的工作。如果您 运行 一直遇到问题或想讨论其他解决方法（例如向后移植 1.6.0 修复程序），请联系我们。
1.7.0 已发布，因此现在应该修复此问题 https://cloud.google.com/dataflow/release-notes/release-notes-java
