----------------------------------
Assignee: (was: Thomas Weise)
> 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
> Labels: apex-runner, contribution-guide
> Fix For: Not applicable
>
>
> 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.
> Error message:
> _[ERROR] Tests run: 2, Failures: 1, Errors: 0, Skipped: 0, Time elapsed:
