Subject [GitHub] flink pull request: [FLINK-3261] Allow Task to decline checkpoint ...

    Looks cool. 
    Just so I understand exactly, what is wrong again if the Coordinator simply aborts expired
checkpoint attempts? Wouldn't the protocol be the same, with less messages? If a task is not
ready it can simply discard the checkpoint request which will eventually time out at the Coordinator.
The Coordinator attempts might potentially keep timing out but there will be a complete snapshot
eventually when all tasks are ready.
