> Key: FLINK-37018
> URL: https://issues.apache.org/jira/browse/FLINK-37018
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.18.0
> Reporter: Sai Sharath Dandi
> Priority: Major
> Attachments: jobmanager.log
>
>
> We observe that a single rescale event from autoscaler triggers multiple
> internal restarts by the adaptive scheduler despite the job not having any
> other reason/exception for internal restarts. There can be 2-3 restarts over
> a very short period (1-2 mins) before the job stabilizes.
> In the attached job manager logs, we can see there are
> # Can change the parallelism of job. Restarting job. (17 times)
> # Received resource requirements from job (7 times).
>
> The job was internal restarted 17 times despite receiving only 7 requests
> from the autoscaler for rescalings
