Hi all,

I‘m running the job example 
https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

apiVersion: batch/v1
kind: Job
metadata:
  name: pi
spec:
  template:
    metadata:
      name: pi
    spec:
      containers:
      - name: pi
        image: perl
        command: ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
      restartPolicy: Never

I got some warning

Why start so many pod and delete it?

I can't delete the job
[root@c3-sa-i2-20151229-buf023 ~]# kubectl delete job pi
error: timed out waiting for "pi" to be synced
