Mayumi Liyanage created BEAM-3319:
-------------------------------------
Summary: Cannot build Apache Beam due to Apex Runner test failing
Key: BEAM-3319
URL: https://issues.apache.org/jira/browse/BEAM-3319
Project: Beam
Issue Type: Bug
Components: runner-apex
Affects Versions: 2.2.0
Reporter: Mayumi Liyanage
Priority: Critical
In contribution-guide to setup Apache Beam, last step indicates to run _mvn
verify_ to make the setup is correct. Build fails due to assertion that is
happening in _org.apache.beam.runners.apex.examples.WordCountTest_. Failure is
due to race condition of not waiting enough for files to be generated. To prove
this bug, if we insert Thread.sleep before the assertion, test always passes.
This is preventing from completing contribution-guide successfully.
