-------------------------------------
Summary: CheckpointIDCounter.shutdown should expose errors
asynchronously
Key: FLINK-26741
URL: https://issues.apache.org/jira/browse/FLINK-26741
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Reporter: Matthias Pohl
{{CheckpointIDCounter.shutdown}} should return a {{CompletableFuture}} exposing
errors if anything happens to enable retrying of the cleanup.
All implementations should also work in an idempotent fashion, i.e. nothing
should happen if the artifact was already deleted.
This bug is not considered a 1.15 blocker because unit tests rerunning the
shutdown worked properly already, i.e. in the worst case (of an error) we would
just miss to clean up right now.
