> Key: BEAM-3757
> URL: https://issues.apache.org/jira/browse/BEAM-3757
> Project: Beam
> Issue Type: Bug
> Components: runner-dataflow
> Affects Versions: 2.2.0
> Environment: gcp, macos
> Reporter: Jonathan Delfour
> Assignee: Thomas Groh
> Priority: Major
>
> Hi,
> First issue is that the beam 2.3.0 python SDK is apparently not working on
> GCP. It gets stuck:
> {noformat}
> Workflow failed. Causes: (bf832d44290fbf41): The Dataflow appears to be
> stuck. You can get help with Cloud Dataflow at
> https://cloud.google.com/dataflow/support.
> {noformat}
> I tried two times.
> Reverting back to 2.2.0: it usually works but today, after > 1 hour of
> processing, and 30 workers used, I get a failure with these in the logs:
> {noformat}

> For the flow, I am extracting data from BQ, cleaning using pandas, exporting
> as a csv file, gzipping and uploading the compressed file to a bucket using
> decompressive transcoding (csv export, gzip compression and upload are in the
> same 'worker' as they are done in the same beam.DoFn).
> PS: i can't find a reasonable way to export the logs from GCP but i can
> privately send the log file i have of the run on my machine (the log of the
> pipeline)
