Error while installing Data Services

@Oren Welcome to the Cloudera Community!

Hello @Oren 

Thank you for reaching out to the community

Please double-check the following especially vault.localhost.localdomain’s ping should be resolved

https://docs.cloudera.com/cdp-private-cloud-data-services/1.5.4/installation-ecs/topics/cdppvc-installation-ecs-steps.html

Checks to make sure there are less than 3 nameserver entries in the /etc/resolv.conf file, and checks the connections to the Cloudera Manager cluster and the CDP console. It also checks to see if vault.localhost.localdomain’s ping can be resolved. If not, it is likely that the host /etc/nsswitch.conf file is misconfigured.
If this inspection fails:

Check the /etc/resolv.conf and /etc/nsswitch.conf files and ensure that /etc/resolv.conf does not contain 3 or more nameservers, and that /etc/nsswitch.conf must contain myhostname under the hosts field.
Check to see if the connections were resolved correctly. If connection to the CDP console fails, check to see if your DNS wildcard is configured properly.

 Let us know if you have any further queries

Hello @shaihavivqlik 

That's really strange. Usually, this error occurs when we cannot lookup 

vault.localhost.localdomain

Can you check your /etc/hosts as well? Also, try pinging your CM server as well

 Something is for sure wrong in the DNS records. I don't we can check any logs as this is failing at the pre-reqs itself

Hello,

Thank you for your update

Can you please confirm if you are able to ping localhost 

# nslookup localhost

How many nameservers are present in /etc/resolv.conf

So here is the error localhost is not resolving 

Please fix the /etc/hosts from any of the working node

Check if the below lines are added or not

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

Can you please fix the localhost thing

nslookup localhost should resolve

we have passed  all pre-requisistes, still facint the same issue

Hello @Rafiy 

Can you please which issue are you facing now?

Same one 

    "unable to resolve either the CM url, CDP console, or localhost"

Hello @shaihavivqlik 

Can you also verify if the wildcard dns is set up correctly 

*.apps.myhostname.com

https://docs.cloudera.com/cdp-private-cloud-data-services/1.5.4/installation-ecs/topics/cdppvc-installation-ds-checklist.html

I faced the same error as you this time, and I had the above mentioned problem so please double check this as well
