----------------------------------

             Summary: [Python] Remove mkdir race condition from write_to_dataset 
                 Key: ARROW-1902
                 URL: https://issues.apache.org/jira/browse/ARROW-1902
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Uwe L. Korn
            Assignee: Uwe L. Korn
             Fix For: 0.8.0


If two processes create the same directory tree, one of them might see that a directory does not exist but before the actual call to {{mkdir}} is done, the second process already created the directory. In this case the former process will raise an exception.
