Opentsdb Bigtable

I am using this tool https://github.com/GoogleCloudPlatform/opentsdb-bigtable to deploy opentsdb in GKE and use Bigtable as a backend DB.

I have two Google projects : project A , project B

In Project A : I am able to deploy opentsdb-bigtable successfully and creates Bigtable tables.

In Project B : I am not able to deploy opentsdb-bigtable. The opentsdb-init deployment (https://github.com/GoogleCloudPlatform/opentsdb-bigtable/blob/master/jobs/opentsdb-init.yaml) is throwing the following error

com.google.bigtable.repackaged.com.google.auth.oauth2.ComputeEngineCredentials runningOnComputeEngine INFO: Failed to detect whether we are running on Google Compute Engine. NativeException: java.io.IOException: java.lang.reflect.InvocationTargetException initialize at /hbase-1.4.3/bin/../lib/ruby/hbase/hbase.rb:45 (root) at /hbase-1.4.3/bin/../bin/hirb.rb:118

So far these are the things I have tried :

  • Check default SA permission in GKE and it has Bigtable administration access
  • Created manually bigtable tables with cbt using the SA (This SA is being used the default SA in GKE)
  • Check GKE configuration to make sure it is using to right default SA

As there's no permission issue (apparently) you may have to incorporate an additional code to make the connection as suggested here:

 Configuration config = BigtableConfiguration.configure(PROJECT_ID, INSTANCE_ID);
 config.set(BigtableOptionsFactory.APP_PROFILE_ID_KEY, INSTANCE_ID);
 connection = ConnectionFactory.createConnection(config);

Additionally you might have a block in your cloud DNS, or the workload identity.

For the DNS you can address the issue by creating the DNS records in Cloud DNS for private.googleapis.com
