--------------------------------------

             Summary: "v1.proto" is already registered error for golang dataflow
                 Key: BEAM-12158
                 URL: https://issues.apache.org/jira/browse/BEAM-12158
             Project: Beam
          Issue Type: Bug
          Components: sdk-go
            Reporter: Kazuki Nishiura


I tried to run wordcount example in go [https://beam.apache.org/get-started/quickstart-go/]

It worked fine in dev but when I try to run it on GCP dataflow, I got '"v1.proto" is already registered' error and job crashes. 

 

It seems proto definition here is using very generic package name "v1" which I suspect is a cause of issue

https://github.com/apache/beam/blob/v2.28.0/sdks/go/pkg/beam/io/pubsubio/v1/v1.proto

 

Here is log in GCP
