    Thanks for the input. I read the code. There are two ways a checkpoint 
fails (as per my code understanding). If for some reason checkpointing cannot 
be performed we send DeclineCheckpoint message. That is handled by the 
Checkpointcoordinator.
    Another is if there is an external error in checkpointing and in that case 
we call failExternally. Which transitions the state to FAILED and closes all 
the watchdog, and cancels the invokable also. Now is the intent to track how 
many times this happens and if so track such occurences of failure and then 
fail the execution graph?


> Checkpoint Coordinator should fail ExecutionGraph after "n" unsuccessful 
> checkpoints

> The Checkpoint coordinator should track the number of consecutive 
> unsuccessful checkpoints.
> If more than {{n}} (configured value) checkpoints fail in a row, it should 
> call {{fail()}} on the execution graph to trigger a recovery.
