-----------------------------------------
Summary: Beam Python integration test suites are flaky:
ModuleNotFoundError
Key: BEAM-7527
URL: https://issues.apache.org/jira/browse/BEAM-7527
Project: Beam
Issue Type: Bug
Components: test-failures
Reporter: Valentyn Tymofieiev
I am seeing several errors in Python SDK Integration test suites, such as
Dataflow ValidatesRunner and Python PostCommit that fail due to one of the
autogenerated files not being found.
For example:

The rootcause is not clear, I suspect that it may be related to the way we
parallelize execution of Python test suites for 2.7, 3.5, 3.6, 3.7.
