[GitHub] [beam] kennknowles opened a new issue, #18165: GcsUtil can try to execute empty batches in some cases.

kennknowles opened a new issue, #18165:
URL: https://github.com/apache/beam/issues/18165

   I think, but have not confirmed, that this happens because we try to remove an empty set of files.
