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.
