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.

Suppose I have a working Flink cluster with 1 taskmanager and 1
jobmanager and I have enabled checkpointing with say an interval of 1
Now if I shut down the Flink cluster in between checkpoints (say for
some upgrade), will the JobManager automatically trigger a checkpoint
before going down?
Or is it mandatory to manually trigger savepoints in these cases?
Also am I correct in my understanding that if a taskmanager goes down
first, there is no way the TaskManager can trigger the checkpoint on
