zhoufek opened a new issue, #31910: URL: https://github.com/apache/beam/issues/31910
### What happened? In the Python container, if the [call to cmd.Start()](https://github.com/apache/beam/blob/2d6d55b98cef5eacc4abd93863de2132cf89bea2/sdks/python/container/boot.go#L330) fails, then it can lead to crash when [trying to access the process's PID](https://github.com/apache/beam/blob/2d6d55b98cef5eacc4abd93863de2132cf89bea2/sdks/python/container/boot.go#L286), since the process is [only set if the call succeeds](https://pkg.go.dev/os/exec#Cmd.Start). It doesn't appear that the cause ever makes it to logs, making it difficult to tell what went wrong. Error handling here should be better. ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [X] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [X] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
