Brian Hulette created BEAM-12515:
------------------------------------
Summary: Python PreCommit flaking in
PipelineOptionsTest.test_display_data
Key: BEAM-12515
URL: https://issues.apache.org/jira/browse/BEAM-12515
Project: Beam
Issue Type: Bug
Components: sdk-py-core, test-failures
Reporter: Brian Hulette
Seeing this failure pretty frequently on PreCommit since yesterday (06/17).
The first failure in precommit cron was here:
https://ci-beam.apache.org/job/beam_PreCommit_Python_cron/4327/
Seems related to BEAM-10006, but I'm not sure what changed to make this start
flaking recently.
