Yun Tang updated FLINK-16443: ----------------------------- Fix Version/s: 1.12.2 > 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 > Assignee: Arvid Heise > Priority: Major > Labels: pull-request-available > Fix For: 1.13.0, 1.12.2 > > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
