hjtran opened a new issue, #36847: URL: https://github.com/apache/beam/issues/36847
### What happened? If you start many pipelines at the same time, it's possible to run into a FileExistsError race condition when two pipelines try to create the requirements cache at the same time: ``` File ".../lib/python3.11/site-packages/apache_beam/runners/runner.py", line 182, in run_pipeline default_environment=self.default_environment(options)), ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ".../lib/python3.11/site-packages/apache_beam/runners/runner.py", line 163, in default_environment return environments.Environment.from_options( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ".../lib/python3.11/site-packages/apache_beam/transforms/environments.py", line 274, in from_options return env_class.from_options(portable_options) # type: ignore ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ".../lib/python3.11/site-packages/apache_beam/transforms/environments.py", line 367, in from_options artifacts=python_sdk_dependencies(options), ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ".../lib/python3.11/site-packages/apache_beam/transforms/environments.py", line 913, in python_sdk_dependencies return stager.Stager.create_job_resources( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ".../lib/python3.11/site-packages/apache_beam/runners/portability/stager.py", line 221, in create_job_resources os.makedirs(requirements_cache_path) File "<frozen os>", line 225, in makedirs FileExistsError: [Errno 17] File exists: '/tmp/dataflow-requirements-cache ``` I think we can probably just set `exists_ok=True` for the. makedirs call ### 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: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
