[jira] [Created] (FLINK-16443) Fix wrong fix for user-code
CheckpointExceptions
Stephan Ewen created FLINK-16443:
------------------------------------
Summary: 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
Fix For: 1.11.0
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.
