@Geoffrey Shelton Okot Thank you. I have tried the above and I am still getting the same errors. Do I need to disable Kerberos and repeat the process of configuration/enabling Kerberos with the above mentioned Realm value(s)? Thank you very much for your assistance. ... View more

@Geoffrey Shelton Okot Thank you for your reply. I am using an existing Active Directory. I made sure of the following: Ambari Server and cluster hosts have network access to, and be able to resolve the DNS names of, the Domain Controllers. Active Directory secure LDAP (LDAPS) connectivity has been configured. Active Directory User container for service principals has been created and is on-hand. For example, "OU=Hadoop,OU=People,dc=apache,dc=org" Active Directory administrative credentials with delegated control of “Create, delete, and manage user accounts” on the previously mentioned User container are on-hand. After following all of the documentation, I enabled Kerberos on the cluster from the Ambari dashboard. The process was able to create all of the principals in the designated container in Active Directory. I am attaching the krb5.conf and an example of the errors I receive when services attempt to start. There is no kdc.conf or kadm5.acl as I am using Active directory as my KDC. Thank you very much.krb5conf.pngerror-example.jpeg ... View more
