Hi, I am trying to figure out why AutoScaler is not working. I have deployed my Flink job on Yarn using AWS EMR.
My configurations are: job.autoscaler.enabled: 'true' job.autoscaler.decision.interval: 10m job.autoscaler.stabilization.interval: 50m job.autoscaler.vertex.min-parallelism: 35 jobmanager.scheduler: adaptive jobmanager.adaptive-scheduler.combined-restart.enabled: true jobmanager.adaptive-scheduler.combined-restart.window-interval: 10m In the job manager log I see this: 2025-09-10 07:33:14,198 INFO org.apache.flink.runtime.scheduler.autoscaler. Autoscaler [] - Scaling Metrics History for job 2705bd9bac1ad0498aa5983c3ca55b82 is empty 2025-09-10 07:33:14,198 INFO org.apache.flink.runtime.scheduler.autoscaler. Autoscaler [] - Empty Metric History for job 2705bd9bac1ad0498aa5983c3ca55b82, so not evaluating. Is there something I should check ? I remember while back the autoscaler was working when I was going with default values for intervals, and I found it too aggressive. So I relaxed these intervals and after that I don't see this working. Is there any issue with my configs causing it to not work ? Thanks Sachin
