Hi, Running Flink 1.15 in application mode, when stop-with-savepointing a job, we encountered a case where a savepoint directory was created, but was empty (we're storing the savepoint on S3, the empty directory marker exists, but neither the _metadata file nor any state files exist).
What can cause this state, and did the job actually savepoint when this happens? What, if any, atomicity occurs in writing savepoints? Best, Max
