I launched the HDPCA practice exam in AWS and the there is a task to add 'node1'.
While adding a new node using ambari, I have to mention the FQDN.
This detail is not mentioned in the exam task html file.
How do I find FQDN ?
P.S. I am able to ssh into node1.
Update: I tried using the following command to get fqdn
This command also gave me the response as "node1". When I mention node1 as the FQDN in Ambari, I get the following warning message:
"node1 is not a valid FQDN. Do you want to continue ?"
This error message is confusing me regarding the FQDN.
When I ignored the above warning, after install, the host check is failing.
As it turns out, the command to find out FQDN is
Even though I ignored all the warning and proceeded to next steps to add the node to the cluster, in the end it all worked well and post intall test was successful.
So I guess this can be ignored for practice exam.
