Hi Robert, I appreciate you having a look. I’ll have a closer look and see what I can find. Thanks!

The JobManager actually received 2 job submissions. There are 2 relevant log messages. 1. "Received JobGraph submission xxx" 2. "Submitting job" 1 is logged right after the dispatcher receives the JobGraph, before the duplicate submission check is done. 2 is logged once we know that there is no duplicate job. We have the following log messages (which you actually posted in here on the list already) TYPE 1: 2021-01-20 14:06:58,225 INFO [flink-akka.actor.default-dispatcher-91] org.apache.flink.runtime.dispatcher.StandaloneDispatcher - Received JobGraph submission 8e1c2fdd68feee100d8fee003efef3e2 (Flink Java Job at Wed Jan 20 14:01:42 EST 2021).

So at 14:06, you are submitting the job, at 14:09 it fails. In between (14:08) you are trying to submit the job again, which gets (rightfully) rejected. It seems that the second submission didn't get logged properly in your client. I don't think there's a bug on Flink's side of things.

I’ve included the JobManager and client application logs there. We have a thread pool that we use to submit multiple jobs in parallel, but in there there’s no retry logic – if any one job fails, it’s an overall failure for the entire application. In regards to the timespan between when the job was logged to have been initially submitted from the client app logs and when the JobManager logs it as being received – we’re submitting a large number of jobs as a part of this application. Is it possible that it’s busy processing other jobs? // ah From: Robert Metzger <rmetz...@apache.org<mailto:rmetz...@apache.org>> Sent: Thursday, January 21, 2021 10:00 AM To: Hailu, Andreas [Engineering] <andreas.ha...@ny.email.gs.com<mailto:andreas.ha...@ny.email.gs.com>> Cc: user@flink.apache.org<mailto:user@flink.apache.org> Subject: Re: org.apache.flink.runtime.client.JobSubmissionException: Job has already been submitted Thanks a lot for your message. Why is there a difference of 5 minutes between the timestamp of the job submission from the client to the timestamp on the JobManager where the submission is received? Is there any service / custom logic involved in the job submission? (e.g. a proxy in between, that has some retry mechanism, or some custom code that does retries?) Could you provide the full JobManager logs of that timeframe, not just those messages filtered for 8e1c2fdd68feee100d8fee003efef3e2?
