> Project: Flink
> Issue Type: Sub-task
> Components: State Backends, Checkpointing
> Reporter: Stephan Ewen
> Assignee: Stefan Richter
> Priority: Major
> Fix For: 1.4.0
>
>
> Operators should try/catch exceptions in the synchronous and asynchronous
> part of the checkpoint and send a {{DeclineCheckpoint}} message as a result.
> The decline message should have the failure cause attached to it.
> The checkpoint barrier should be sent anyways as a first step before
> attempting to make a state checkpoint, to make sure that downstream operators
> do not block in alignment.
