Canbin Zheng updated FLINK-17177:
---------------------------------
Description: 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 is 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 a new {{Watcher}} immediately. (was:
