I found it necessary to troubleshoot a problem enabling kerberos to modify the ambari server and cluster boxes /etc/hostname from name.example.com to name.corp.example.com I also edited the /etc/hosts on all to reflect accordingly. I also ran ambari-server setup-security and option 1 to DISABLE the https. How do I remove current host which are still named without *.corp.* and remake my cluster please? thanks!

problem seems to be with this two-hosted DNS domain.....what if instead of using the ambari.example.com we use the corp.example.com all around with other hosts... so change their fqdn to ambari.corp.example.com, cpmpute1.corp.example.com I feel like spinning wheels trying to get it to work wiht short name,

Ambari server URL changed. To make use of the Tez View in Ambari please update the property tez.tez-ui.history-url.base in tez-site
Adjusting ambari-server permissions and ownership...
NOTE: Restart Ambari Server to apply changes ("ambari-server restart|stop+start") restarted the ambari service #ambari-server restart| Now I get the login page on port 8- butif I try to login as admin the screen just freezes and mouse cursor becomes circle with line through it. Any suggestions welcome to get back to admin able to log in.

I sort of expected to see the ambari server listed in Hosts....no-ambari-in-hosts.png incorect assumption? anyhow I suppose does nto matter since you said is not needed to enable kerberos. we can put this to bed if you like ,thanks!

Actually I cannot find the ambari agent on the ambari server host. the log I showed is from another member server, So just to backup a se. when I try to enable the kerberos... I get the hostname fail as the first error , this happens on the ambari server it says.... this is what led me to the conclusion that I need to add the ambari server tot he cluster which is why I opened that other question. maybe this pic will helphorton-err-obfu-1.pdf

The host I cannot join to cluster is the Ambari server itself , I thought this was needed fro my reading of docs for the cluster in order to run the enable kerberos wizard. But seems not needed from your previous comment. I can run the command regardless , here are returns form one member compute1 root@compute1:~# dpkg --list | grep ambari ii ambari-agent 2.7.3.0-139 amd64 Ambari Agent

Hi Jay thanks. Above is the error log from /var/log/ambari-server/ambari-server.log I added removed the corp/example/.cpom entries from /etc/hosts Aside questions of anyone can answer... : Is there any documentation to suggest that you cannot use ubuntu 18.04 as the server? every doc I read does not reference this version, seems to stop at ubuntu 12 or 14... Does the ambari server need to be host member of cluster? ...

Hi Jay , thanks for reply.
I changed /etc/hosts on ambari to reflect your suggestion ( I have not done all in cluster as yet)
10.x.x.x ambari.example.com
trie to enable , still returns error on creating principles for ambari ....the error from /var/log/ambari-server/ambari-server.log is below. ( is there anyplace else to look?)

At wits end wit this hortwork work platform , trying to get it kerborized.
The phase where it Testing Kerberos clients, keep getting this error that it cannot find the ambari host and displays the fqdn
The ambari host is name resolved by 2 hosted domains internally with no problem. ie ambari.example.com and ambari.corp.example.com. I also added this in /etc/hosts files on each server in cluster including ambari server , each maser node , slave node and DC on our network to eliminate DNS as an issue ( which I cannot believe it is as at teh command line these things can resolve all day long to each other) What logs can I examine to give more information on this error please?
var/log/ambari-server is not much help
