> Key: BEAM-8149
> URL: https://issues.apache.org/jira/browse/BEAM-8149
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Affects Versions: 2.15.0
> Reporter: Hannah Jiang
> Assignee: Hannah Jiang
> Priority: P2
> Labels: stale-assigned
>
> The multi-process runner does not handle SIGINT gracefully. To reproduce, run
> wordcount.py using the "Run with multiprocessing mode" instructions from the
> first comment in BEAM-3645 (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}
