[jira] [Created] (CRUNCH-652) SourceTargetHelperTest became flaky when upgrading to hadoop 3.0.0

Gergo Repas created CRUNCH-652:
----------------------------------

             Summary: SourceTargetHelperTest became flaky when upgrading to hadoop 3.0.0
                 Key: CRUNCH-652
                 URL: https://issues.apache.org/jira/browse/CRUNCH-652
             Project: Crunch
          Issue Type: Bug
            Reporter: Gergo Repas
            Priority: Minor


Problem description: org.apache.crunch.io.SourceTargetHelperTest became flaky - it failed when its testGetNonExistentPathSize_NonExistantPath() method ran first

Root cause: due to upgrading the hadoop version to 3.0.0, the org.apache.hadoop.fs.FsTracer singleton has been pulled in, which throws an NPE when initialized with a filesystem that has null configuration. SourceTargetHelperTest.MockFileSystem.fs has null configuration.
