authentication - Google Cloud Dataflow错误：“应用程序默认凭据不可用”

我们有一个Google Cloud Dataflow作业，该作业写入Bigtable（通过HBase API）。不幸的是，由于以下原因导致失败：

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$1.<init>(CloudBigtableConnectionPool.java:72) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.createConnection(CloudBigtableConnectionPool.java:72) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.getConnection(CloudBigtableConnectionPool.java:64) at com.google.cloud.bigtable.dataflow.CloudBigtableConnectionPool.getConnection(CloudBigtableConnectionPool.java:57) at com.google.cloud.bigtable.dataflow.AbstractCloudBigtableTableDoFn.getConnection(AbstractCloudBigtableTableDoFn.java:96) at com.google.cloud.bigtable.dataflow.CloudBigtableIO$CloudBigtableSingleTableBufferedWriteFn.getBufferedMutator(CloudBigtableIO.java:836) at com.google.cloud.bigtable.dataflow.CloudBigtableIO$CloudBigtableSingleTableBufferedWriteFn.processElement(CloudBigtableIO.java:861)

这没什么意义，因为该作业已在云数据流服务/虚拟机上运行。

我们正在使用bigtable-hbase-dataflow版本0.3.0，我们希望使用HBase API。
