-----------------------------------
Thanks [~ouyangwuli] for sharing the investigation. +1 for adding the
resourceVersion=0 when doing the list pods.
> Avoid to create watcher without the resourceVersion

> Currently, we create the watcher in KubernetesResourceManager. But it do not
> pass the resourceVersion parameter, it will trigger a request to etcd. It
> will bring the burden to the etcd in large scale cluster (which have been
> seen in our internal k8s cluster). More detail can be found
> [here|https://kubernetes.io/docs/reference/using-api/api-concepts/#the-resourceversion-parameter]
>
> I think we could use the informer to improve it (which will spawn a
> list-watch and maintain the resourceVersion internally)
