Stephan Ewen resolved FLINK-4323.
---------------------------------
Resolution: Invalid
Shutdown hook is only installed in "standalone" mode, which in the
high-availability context means "non high-availability" mode
> 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.
