Do we need to configure anything for DNS for Embedded Container Service (ECS)? Or do we need to configure anything in k8s pods?

Hello @steinsgate

Thank you for raising this

This looks to be a DNS issue on the host, Have you configured the DNS as per the below on the host

The cluster generates multiple hosts and host based routing is used in the cluster in order to route it to the right service. You must decide on a domain for the services which Cloudera Manager by default points to one of the host names on the cluster. However, during the installation, you should check the default domain and override the default domain (only if necessary) with what you plan to use as the domain. The default domain must have a wildcard DNS entry. For example, “*.apps.myhostname.com”.
It is recommended that you leave IPv6 enabled at the OS level on all ECS nodes.

https://docs.cloudera.com/cdp-private-cloud-data-services/1.5.3/installation-ecs/topics/cdppvc-installation-ecs-software-requirements.html

Can you please re-check if the pre-reqs have been set up correctly.

Hello @steinsgate

Thank you for your update

Yes please ensure that the DNS configuration is correct on the nodes. I mean to say that it should adhere to our documentation.

Also, try resolving the hostname manually using nslookup from the nodes and compare the output from the working nodes and see if that works
