Subject Re: Checkpointing on cluster shutdown

No checkpoint will be triggered when the cluster is shutdown. For this 
case you will have to manually trigger a savepoint.

If a TM goes down it does not create a checkpoint. IN these cases the 
job will be restarted from the last successful checkpoint.
