Labels: pull-request-available (was: )
> Fix wrong fix for user-code CheckpointExceptions
> ------------------------------------------------
>
> Key: FLINK-16443
> URL: https://issues.apache.org/jira/browse/FLINK-16443
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Reporter: Stephan Ewen
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> The problem of having exceptions that are only in the user code classloader
> was fixed by proactively serializing them inside the {{CheckpointException}}.
> That means all consumers of {{CheckpointException}} now need to be aware of
> that and unwrap the serializable exception.
> I believe the right way to fix this would have been to use a
> SerializedException in the {{DeclineCheckpoint}} message instead, which would
> have localized the change to the actual problem: RPC transport.
> I would suggest to revert https://github.com/apache/flink/pull/9742 and
> instead apply the above described change.
