Yang Wang commented on FLINK-17177:
-----------------------------------
{code:java}
Object is: If Type is Added or Modified: the new state of the object. If Type
is Deleted: the state of the object immediately before deletion. If Type is
Error: Status is recommended; other types may make sense depending on context.
{code}
I post the {{WatchEvent}} in K8s here[1]. I do not find the "Error" type means
"HTTP error". So could share some information about how the "Error" type is
introduced by HTTP layer error?

> Key: FLINK-17177
> URL: https://issues.apache.org/jira/browse/FLINK-17177
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Affects Versions: 1.10.0, 1.10.1
> Reporter: Canbin Zheng
> Priority: Major
> Fix For: 1.11.0
>
>
> Currently, once we receive an *ERROR* event that is sent from the K8s API
> server via the K8s {{Watcher}}, then {{KubernetesResourceManager#onError}}
> will handle it by calling the
> {{KubernetesResourceManager#removePodIfTerminated}}. This may be incorrect
> since the *ERROR* event indicates an exception in the HTTP layer that is
> caused by the K8s Server, which means the previously created {{Watcher}} may
> be no longer available and we'd better re-create the {{Watcher}} immediately.
