-----------------------------------
Assignee: boshu Zheng
> Log stack trace on declined/discarded checkpoint
> ------------------------------------------------
>
> Key: FLINK-11190
> URL: https://issues.apache.org/jira/browse/FLINK-11190
> Project: Flink
> Issue Type: Improvement
> Environment: Flink 1.5.2
> Reporter: Daniel Harper
> Assignee: boshu Zheng
> Priority: Trivial
>
> When setting the configuration
> [failOnCheckpointingErrors|https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/CheckpointConfig.java#L248],
> any checkpoints that are declined don't appear to print the stack trace for
> the exception that was thrown.
> The current code appears to print a descriptive message, but not the actual
> underlying cause of why the checkpoint failed in the first place.
> https://github.com/apache/flink/blob/release-1.5.2/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/CheckpointCoordinator.java#L1255
> This would be useful for trying to determine reasons for failure so we can
> take steps to improve the reliability of checkpointing (even though the
> setting 'failOnCheckpointingErrors' is set, it would still be useful to see
> the causes of checkpoint failures)
