Description DeShuai Ma 2015-11-04 06:38:44 UTC 
Description of problem:
Create a hpa then describe it, the "Min pods" number is overflow.

Version-Release number of selected component (if applicable):
openshift v1.0.7-203-geebdecd
kubernetes v1.2.0-alpha.1-1107-g4c8e6f4

How reproducible:
Always

Steps to Reproduce:
1.Create a hpa
[fedora@ip-172-18-15-150 sample-app]$ cat hpa.yaml 
apiVersion: extensions/v1beta1
kind: HorizontalPodAutoscaler
metadata:
  name: php-apache
spec:
  maxReplicas: 10
  minReplicas: 1
  scaleRef:
    kind: ReplicationController
    name: php-apache
    namespace: default
  cpuUtilization:
    targetPercentage: 10
$ oc create -f hpa.yaml -n dma

2.Describe the hpa
[fedora@ip-172-18-15-150 sample-app]$ oc describe hpa/php-apache -n dma
Name:				php-apache
Namespace:			dma
Labels:				<none>
CreationTimestamp:		Wed, 04 Nov 2015 01:51:00 +0000
Reference:			DeploymentConfig/default/php-apache/
Target CPU utilization:		10%
Current CPU utilization:	<not available>
Min pods:			859533940640
Max pods:			10

Actual results:
2.The Min pods is 859533940640

Expected results:
2.The Min pods should is 1

Additional info:
Should cherry-pick from upstream pr https://github.com/kubernetes/kubernetes/pull/16025
