See my reply I just posted to the thread "Flink 1.7 jobmanager
tries to lookup taskmanager by its hostname in k8s environment".

I have been working with Flink under Kubernetes recently
and I have run into some problems with metrics. I think I
have it figured out though. It appears that it's trying to
use hostname resolution for the jobmanagers. This causes
this error:
Association with remote system
[akka.tcp://flink@flink-taskmanager-7dffcf7975-vb2pc:42028]
has failed, address is now gated for [50] ms. Reason:
[Association failed with

Caused by: [flink-taskmanager-7dffcf7975-vb2pc]
I noticed that if I put hosts file entries on the
jobmanager for each of the task managers then everything
started working. Is there a way to specify the hostname of
taskmanager like you can with the jobmanager?
