---------------------------------
Summary: warn or error when constructor runner != options runner
Key: BEAM-9438
URL: https://issues.apache.org/jira/browse/BEAM-9438
Project: Beam
Issue Type: Improvement
Components: sdk-py-core
Reporter: Kyle Weaver
Assignee: Kyle Weaver
Right now, the runner set in the Pipeline constructor silently overrides the
runner set in pipeline options [1]. This can result in subtle errors, where a
different runner is used than expected [2]. I can't imagine any legitimate
reason anyone would want to do this, so we should error when they contradict
each other, or at least warn.
