Kubernetes horizontal pod autoscaling not working

kubectl version Client Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"5cb86ee022267586db386f62781338b0483733b3", GitTreeState:"clean"} Server Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"5cb86ee022267586db386f62781338b0483733b3", GitTreeState:"clean"}

Error log on controller manager: Failed to reconcile hello-world: failed to compute desired number of replicas based on CPU utilization for Deployment/default/hello-world: failed to get CPU utilization: failed to get CPU consumption and request: metrics obtained for 0/3 of pods

I can talk directly to Heapster and get my pod metrics: curl http://$MY_HEAPSTER_SERVICE_IP:8082/api/v1/model/namespaces/default/pods//hello-world-819237062-j0ubt/metrics/cpu-usage 

{
  "metrics": [
   {
    "timestamp": "2016-04-05T16:49:00Z",
    "value": 0
   },
   {
    "timestamp": "2016-04-05T16:48:00Z",
    "value": 0
   }
  ],
  "latestTimestamp": "2016-04-05T16:49:00Z"
 }

As explained in the comment above the Heapster was running in a non-default location, which horizontal pod autoscaler controller did not expect.

I've opened an issue to make it configurable.
