Kyle Weaver created BEAM-8267:
---------------------------------
Summary: Python loopback throws spurious errors on shutdown
Key: BEAM-8267
URL: https://issues.apache.org/jira/browse/BEAM-8267
Project: Beam
Issue Type: Bug
Components: sdk-py-harness
Reporter: Kyle Weaver
Assignee: Kyle Weaver
These errors don't appear to actually cause any problems, but they are
misleading. Looks like we're trying to stop subprocesses even when there _are_
no subprocesses.
