[jira] [Commented] (BEAM-3757) Shuffle read failed using python 2.2.0

    [ https://issues.apache.org/jira/browse/BEAM-3757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16383846#comment-16383846 ] 

Jonathan Delfour commented on BEAM-3757:
----------------------------------------

I have created a support ticket with google team, they confirm it is not isolated and are investigating.
Feel free to close this one, i believe they will contact you should there be an issue with beam itself.

> 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}
> Traceback (most recent call last):

> {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)
