Kazuki Nishiura created BEAM-12158:
--------------------------------------
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
{code:java}
"panic: proto: file "v1.proto" is already registered "
