Yifan Mai updated BEAM-8149:
----------------------------
Description:
The multi-process runner does not handle SIGINT gracefully. To reproduce, run
wordcount.py using the "Run with multiprocessing mode" instructions from the
comment above (in Python 3).
Expected: wordcount terminates gracefully when Ctrl-C is pressed during
pipeline execution (similarly to default direct runner)
Actual: wordcount hangs forever after printing the following once per worker:
{code}
Exception in thread run_worker:
Traceback (most recent call last):
File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
self.run()
File "/usr/lib/python3.6/threading.py", line 864, in run
self._target(*self._args, **self._kwargs)
File
"/usr/local/google/home/yifanmai/venv/wordcount/lib/python3.6/site-packages/apache_beam/runners/portability/local_job_service.py",
line 216, in run
'Worker subprocess exited with return code %s' % p.returncode)
RuntimeError: Worker subprocess exited with return code 1
{code}
