             Summary: Operators should tolerate checkpoint failures
                 Key: FLINK-4809
             Project: Flink
          Issue Type: Sub-task
          Components: State Backends, Checkpointing
            Reporter: Stephan Ewen
             Fix For: 1.2.0

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.
