*Closed* - Cloudbreak on Azure: Kerberize a cluster against Active Directory - error related to length of CN

Contributor

Provisioned a cluster on Azure using Cloudbreak and then...

Attempted:
Kerberize the cluster using Ambari Kerberos automatic wizard, against an existing Active Directory prepped ahead of time

Issue:
The kerberos set up fails when it tries to create a SPN for zookeeper. The error seems to point to length of CN exceeding max length limit.

STDERR from Ambari Kerberos wizard UI:

2017-11-28 16:41:58,340 - Failed to create principal, zookeeper/den-m23.rxo2hisyweyefnkiphzw3u2whg.cx.internal.cloudapp.net@DENALI.COM - 
Can not create principal : zookeeper/den-m23.rxo2hisyweyefnkiphzw3u2whg.cx.internal.cloudapp.net@DENALI.COM

Just to show that several SPs got created, it consistently fails at zookeeper.

Troubleshooting attempted:
Reduced zookeeper to zk, got past the error, only to fail for amshbase, reduced this to amshb, got past the setup.
Failed during smoke testing; We cannot be changing service principal names, this was merely to test the hypothesis that it was length related.

Deduction:
The length is beyond the limit acceptable by Active Directory

Question:

(1) Anyone run into this issue that has a solution to share? I know I can pop a MIT Kerberos KDC in front of AD...looking for options.

(2) Does the Cloudbreak team have any guidance?

Thanks in advance.
I am now attempting to provision via Cloudbreak - kerberize at provision-time against existing Active Directory. Fingers crossed.

Contributor

Solution:
VM FQDN needs to be shorter than what you get with Azure defaults. This is not a Cloudbreak issue.

Attempting to create a HDP cluster with Kerberos at provision time against AD failed.
Issue is tied to the same as one reported - very long VM FQDN - exceeding upper limits defined in AD, AAD DS

I am having the same issue with a kerberized cluster created through cloudbreak 2.7. Did you manage to find a workaround the fqdn length?
