Ufuk Celebi commented on FLINK-4323:
------------------------------------
Should we still remove the shut down hook? The shut down hook would only hide
problems with the {{ExecutionGraph}} cleanup. The {{CheckpointCoordinator}}
should stay independent of the {{RecoveryMode}}.
> Checkpoint Coordinator Removes HA Checkpoints in Shutdown

> Key: FLINK-4323
> URL: https://issues.apache.org/jira/browse/FLINK-4323
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.1.0
> Reporter: Stephan Ewen
> Priority: Blocker
> Fix For: 1.2.0, 1.1.1
>
>
> The {{CheckpointCoordinator}} has a shutdown hook that "shuts down" the
> savepoint store, rather than suspending it.
> As a consequence, HA checkpoints may be lost when the JobManager process
> fails but allows the shutdown hook to run.
> I would suggest to remove the sutdown hook from the CheckpointCoordinator all
> together. The JobManager process is responsible for cleanups and can better
> decide what should be cleaned up and what not.
