[GitHub] [beam] kennknowles opened a new issue, #18663: PackageUtil should retry check for whether file is already staged

[GitBox <gi...@apache.org>]

kennknowles opened a new issue, #18663:
URL: https://github.com/apache/beam/issues/18663

   The code to stage files retries the upload, but the existence (and size) check is attempted only once:
   
   https://github.com/apache/beam/blob/dc3a664e3b4b4f63500954aae25dce0cb5f8b314/runners/google-cloud-dataflow-java/src/main/java/org/apache/beam/runners/dataflow/util/PackageUtil.java#L193
   
   This causes post-commit tests to fail sometimes:
   
   https://builds.apache.org/job/beam_PostCommit_Java_ValidatesRunner_Dataflow/org.apache.beam$beam-runners-google-cloud-dataflow-java/4632/testReport/junit/org.apache.beam.sdk.io/BoundedReadFromUnboundedSourceTest/testDedup/
   
   https://builds.apache.org/job/beam_PostCommit_Java_ValidatesRunner_Dataflow/org.apache.beam$beam-runners-google-cloud-dataflow-java/4636/testReport/junit/org.apache.beam.sdk.transforms/ViewTest/testEmptyMultimapSideInput/
   
   We should retry this check as well.
