> 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.
