title: Kubernetes HPA doesn't scale down after decreasing the loads
body: <p>the Kubernetes HPA works correctly when load of the pod increased but after the load decreased, the scale of deployment doesn't change. This is my HPA file:</p>
  <pre><code>apiVersion: autoscaling/v2beta2
  kind: HorizontalPodAutoscaler
  metadata:
    name: baseinformationmanagement
    namespace: default
  spec:
    scaleTargetRef:
      apiVersion: apps/v1
      kind: Deployment
      name: baseinformationmanagement
    minReplicas: 1
    maxReplicas: 3
    metrics:
    - type: Resource
      resource:
        name: cpu
        target:
          type: Utilization
          averageUtilization: 80
    - type: Resource
      resource:
        name: memory
        target:
          type: Utilization
          averageUtilization: 80
  </code></pre>
  <p>My kubernetes version:</p>
  <pre><code>&gt; kubectl version
  Client Version: version.Info{Major:&quot;1&quot;, Minor:&quot;16&quot;, GitVersion:&quot;v1.16.1&quot;, GitCommit:&quot;d647ddbd755faf07169599a625faf302ffc34458&quot;, GitTreeState:&quot;clean&quot;, BuildDate:&quot;2019-10-02T17:01:15Z&quot;, GoVersion:&quot;go1.12.10&quot;, Compiler:&quot;gc&quot;, Platform:&quot;linux/amd64&quot;}

  <p>And this is my HPA describe:</p>
  <pre><code>&gt; kubectl describe hpa baseinformationmanagement
