-------------------------------------
Summary: Log stack trace on declined 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
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)
