damccorm opened a new issue, #21269:
URL: https://github.com/apache/beam/issues/21269

   Until version 2.33.0 of Apache Beam, (tested with a Python streaming 
pipeline consuming events from PubSub and writing them into GCS), some files 
were being deleted from the temporary folder before being moved to the 
destination. This was the original issue: 
   
   https://issues.apache.org/jira/browse/BEAM-12950
   
   In version 2.34.0 we applied a temporary workaround to be sure that no data 
is dropped. Instead of deleting the orphaned files, we just log them:
   
   
[https://github.com/apache/beam/pull/15576](https://github.com/apache/beam/pull/15576)
   
   Most probably the root cause of the missing event was that we were removing 
files at an erroneous time. We need to delete orphaned files in a subsequent 
step (after we're sure that there won't be retries). 
   
   Once the original issue is fixed and the orphaned files are deleted at the 
correct time, we should remove the decorator of the unit test skipped in the 
Pull Request above.
