kdc-unreachable.jpgI am trying to kereeberise my HDP cluster. I have installed a KDC on the ambari host itself and i want to use that. so i selected option 1 (existing KDC) in ambari. But when i try to test the KDC connection it fails and i get the following error. 23 Mar 2016 13:16:29,457 WARN [qtp-ambari-client-18131] KdcServerConnectionVerification:187 - An unexpected exception occurred while attempting to communicate with the KDC server at hostname:88 over TCP
23 Mar 2016 13:16:29,459 WARN [qtp-ambari-client-18131] KdcServerConnectionVerification:187 - An unexpected exception occurred while attempting to communicate with the KDC server at hostname:88 over UDP
23 Mar 2016 13:16:29,460 ERROR [qtp-ambari-client-18131] KdcServerConnectionVerification:113 - Failed to connect to the KDC at hostname:88 using either TCP or UDP But when i try to do kinit or invoke any kerberos command from the ambari/KDC host it is working fine. It is pretty strange and i dont see any network related issues. this error is seen only when a wrong kdc information is provided. But in my case even after providing the correct details it fails. From the logs i couldnt trace anything. Is there any way to debug or trace it. i used ping, telenet to do the basic checks and everything is fine. P.s i have just replaced my KDC host names with the string "hostname"in the above error message.
