Ahmet Altay created BEAM-539:
--------------------------------

             Summary: Error when writing to the root of a GCS location
                 Key: BEAM-539
                 URL: https://issues.apache.org/jira/browse/BEAM-539
             Project: Beam
          Issue Type: Bug
          Components: sdk-py
            Reporter: Ahmet Altay
            Assignee: Chamikara Jayalath
            Priority: Minor


User issue: http://stackoverflow.com/questions/38811152/google-dataflow-python-pipeline-write-failure

Reproduction: use a TextFileSink and set output locations as gs://mybucket and it fails. Change
it to gs://mybucket/ and it works.

The final output path is generated here:
https://github.com/apache/incubator-beam/blob/python-sdk/sdks/python/apache_beam/io/fileio.py#L495

And this seemingly works in the Java SDK.

Stack:
