Stephan Ewen created FLINK-9279:
-----------------------------------

             Summary: PythonPlanBinderTest flakey
                 Key: FLINK-9279
                 URL: https://issues.apache.org/jira/browse/FLINK-9279
             Project: Flink
          Issue Type: Bug
          Components: Python API, Tests
    Affects Versions: 1.5.0
            Reporter: Stephan Ewen


The test fails while trying to create the parent directory {{/tmp/flink}}. That happens if a file with that name already exists.

The Python Plan binder apparently used a fix name for the temp directory, but should use a statistically unique random name instead.

Full test run log: https://api.travis-ci.org/v3/job/373120733/log.txt
