---------------------------------
Summary: Trigger checkpoint failed but it were shown as COMPLETED
by rest API
Key: FLINK-31077
URL: https://issues.apache.org/jira/browse/FLINK-31077
Project: Flink
Issue Type: Bug
Components: Runtime / Checkpointing
Affects Versions: 1.16.1, 1.15.3, 1.17.0
Reporter: Junrui Li
Fix For: 1.17.0, 1.15.4, 1.16.2
Currently, we can trigger a checkpoint and poll the status of the checkpoint
until it is finished by rest according to FLINK-27101. However, even if the
checkpoint status returned by rest is completed, it does not mean that the
checkpoint is really completed. If an exception occurs after marking the
pendingCheckpoint
completed([here|https://github.com/apache/flink/blob/bf0ad52cbcb052961c54c94c7013f5ac0110ef8a/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/CheckpointCoordinator.java#L1309]),
the checkpoint is not written to the HA service and we can not failover from
this checkpoint.
