Description Eric Paris 2017-07-20 11:10:35 EDT
+++ This bug was initially created as a clone of Bug #1471198 +++

I see lots of events like:

Pod Warning   DNSSearchForming   kubelet, ip-172-31-52-130.ec2.internal   Found and omitted duplicated dns domain in host search line: 'cluster.local' during merging with cluster dns domains

1 pod is showing these events more than once per second.

Do we need these at all?
Should they be rate limited? (are they?)
Is this a misconfiguration of some sort?

The rate limiting work we are carrying in Origin pending:
https://github.com/kubernetes/kubernetes/pull/47367

will make a major improvement to the rate of events in this case.

This event serves the cluster operator more than the cluster end-user.

Agree it should be removed.
