----------------------------------------------------------------
Thanks for your attention! [~xintongsong] [~trohrmann] [~fly_in_gis] Given the
following call stack,
{quote}{{ResourceManager#releaseResource}}
- {{KubernetesResourceManager#stopWorker}}
- {{KubernetesResourceManager#internalStopPod}}
- {{ResourceManager#closeTaskManagerConnection}}
{quote}
I think it's enough to explicitly call
{{ResourceManager#closeTaskManagerConnection}} in
{{KubernetesResourceManager#removePodIfTerminated}} for this issue.
