Hi Paul,

Sorry for the late reply. I had a look at the attached log. I think
FLINK-10482 affects the shut down of the "per-job cluster" after all. Here is
the respective stacktrace:

We try to create an ArchivedExecutionGraph, which fails because we cannot
snapshot the checkpoint statistics. The subsequent code that should ultimately
shut down the cluster is not executed [1]. If you can tell us how you run into
the "Negative number of in progress checkpoints" problem, we might be able to
come up with a mitigation until FLINK-10482 is fixed.

Best,
Gary

Hi Gary,

Thanks for your reply and sorry for the delay. The attachment is the jobmanager logs after invoking the cancel command.

I think it might be related to the custom source, because the jobmanager keeps trying to trigger a checkpoint for it,

but in fact it’s already canceled. The source implementation is using a running flag to denote it’s running, and the

cancel method is simply setting the flag to false, which I think is a common way of implementing a custom source.

In addition, the cluster finally shut down because I killed it with yarn commands.

And also thank you for the pointer, I’ll keep tracking this problem.

Best,

Paul Lam

Hi Paul,

Can you share the complete logs, or at least the logs after invoking the
cancel command?

If you want to debug it yourself, check if
MiniDispatcher#jobReachedGloballyTerminalState [1] is invoked, and see how the
jobTerminationFuture is used.

Best,
Gary

Hi,

I’m using Flink 1.5.3, and I’ve seen several times that the detached YARN cluster doesn’t shut down after the job is canceled successfully. The only errors I found in jobmanager’s log are as below (the second one appears multiple times):

```

```

AFAIK, it’s a know issue[1] but should not affect the cluster shutdown. Does anyone meet this problem before? Thanks a lot!
