[This sample](https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/dataflow/run_template/main_test.py) has been having issues in CI/CD because it is shelling out to a subprocess that may or may not be properly configured. I have patched the test for now to configure the shell but this is just a short-term solution. Please replace the `sp` calls with client library calls to avoid regressions in the future.
