I want to enable security to my cluster in ambari (HDP-184.108.40.206) , for that I have followed this link to prepare my Windows KDC.
Environment used – CentOS7 and Windows 2102 KDC.
In Enable Kerberos Wizard, I have entered the Admin KDC credentials then on theStep 7(Kerberize cluster)am facing the issue on creating the principals from the Linux cluster.
Operation(Principal creation), Status(Failed), Reason of failure(Failed to create principal, securecluster-030818@YOURDOMAIN.COM - can not check if principal exists: securecluster-030818@ YOURDOMAIN.COM), RequestId(72), TaskId(807), Principal(securecluster-030818@ YOURDOMAIN.COM)
Please any guide me to resolve this issue or I missed any pre requisites?
