hi Jaimin all the steps you mentioned are for the KDC server , not the client . and all these steps are fine and correct as you said they should be. if they were not correct the 3 other clients would not get installed right ? There must be somethings that Kerberos is expecting on the client hadoop4 which is missing and thus the Kerberos client fails to install there.

the file exists on all nodes [root@hadoop4 ~]# ls -al /etc/krb5.conf -rw-r--r--. 1 root root 553 Dec 28 14:12 /etc/krb5.conf [root@hadoop4 ~]#

in the Install document of Kerberos there is no mention of what to do on client , how can I check if the client is ready to be a Kerberos client ?

aliyesami · ‎12-28-2016

yes its up , since other 4 clients have no issues . and also this node I can connect to port 88 on hadoop1 where kdc server is running [root@hadoop1 ~]# /etc/rc.d/init.d/krb5kdc status krb5kdc (pid 4908) is running... [root@hadoop1 ~]# [root@hadoop4 ~]# nc -vz hadoop1 88 Connection to hadoop1 88 port [tcp/kerberos] succeeded! [root@hadoop4 ~]#

I am enabling Kerberos in Ambari and its failing on one of the clients in a 5 node cluster with the error below capture1.jpg

I am reinstalling Ranger via ambari following an online tutorial but I am not getting the "Configure Identies" screen after "Customize Service" The picture below shows the missing screen from my setup . Why iam not seeing this screen?

thanks I could remove it .

aliyesami · ‎12-28-2016

I have stopped the service and put it in maintenance mode but still if I try to delete it from Ambari nothing happens.'i am using HDP2.5

which of the three options I should choose for non-manual setup ? obviously the last one is out , and I don't have LDAP so should I be choosing "Exisiting MIT KDC" ? but I also don't have this setup , so I am totally lost Use an Existing MIT KDC Use an Existing Active Directory Use Manual Kerberos Setup

I think my problem for failing ranger KMS install was wrong Kerberos setup as you see from the attached screen its complaining about Kerberos being installed manually. So how I do I install Kerberos "NOT manually" ?
