Kerberos:Error occured in generating credentials

[#1]

Hi,

I was enabling kerberos from cloudera manager.

Everything worked fine but when it tried to do the step of "generating Credentials" it gave me an error.

Please find the error.

Any suggestions?

You should not have to specifically add the CM principal, the */admin should handle it.

From what you pasted, I think you have a space missing between your COM and the "*" at the end of the first line;  Mine looks like this: 

[12:34 root@secsme-1 ~] > cat kadm5.acl
*/admin@COE.CLOUDERA.COM *

Just FYI, it should have a space

Yes ,It was a typo error, I meant the space should be there. 🙂
