## What is the purpose of the change The ScalingTracking of autoscaler is wrong, it's always greater than AutoScalerOptions#STABILIZATION_INTERVAL. ### Reason When flink job isStabilizing, ScalingMetricCollector#updateMetrics will return a empty metric history. In the JobAutoScalerImpl#runScalingLogic method, if `collectedMetrics.getMetricHistory().isEmpty()` , we don't update the ScalingTracking. The default value of AutoScalerOptions#STABILIZATION_INTERVAL is 5 min, so the restartTime is always greater than 5 min. However, it's quick when we use rescale api. ## Brief change log Update the scaling tracking even if the job is stabilizing. ## Verifying this change Adding the test later. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changes to the `CustomResourceDescriptors`: no - Core observer or reconciler logic that is regularly executed: no ## Documentation - Does this pull request introduce a new feature? no -- This is an automated message from the Apache Git Service.
