yangzhang75 opened a new issue, #5916:
URL: https://github.com/apache/texera/issues/5916
### What happened?
PR #5597 changed PythonWorkflowWorker to pass the Python worker's startup
config as a single JSON-string command-line argument (e.g.
{"workerId":"w","outputPort":"5000",...}), parsed by
texera_run_python_worker.py via json.loads.
On Windows, the JVM (ProcessBuilder) assembles argv into a single
command-line string, and the inner double quotes are stripped before Python
receives the argument. Python then gets {workerId:w,...} instead of valid JSON
and crashes with:
json.decoder.JSONDecodeError: Expecting property name enclosed in double
quotes
Linux/macOS are unaffected because the JVM passes argv directly without a
shell, so the quotes survive.
Expected: Python worker starts on all platforms.
### How to reproduce?
1. On Windows, run a workflow containing any Python UDF operator.
2. The Python worker process fails to launch; logs show the JSONDecodeError
above.
