API POST Error when Configuring Kerberos through wizard

avatar
Contributor

I am trying to enable Kerberos for my HDP-2.5 cluster. I have been following through the documentation but on the 'Install and Test Kerberos' the test is failing with the error shown below.

I am using an existing MIT KDC which I have installed on a separate box, and the JCE was unzipped for each host in the cluster.

The KDC connection was ok and I can't seem to find any other people with the same issue. Recently SSL was added to Ambari unsure if this is related. I have tried restarting the Kadmin server but with no avail.

Any help is much appreciated.

When you get the above mentioned error in the ambari UI, do you see a complete stackTrace of the error in detail inside the "/var/log/ambari-server/ambari-server.log". Can you please post that error here?

Shouldn't the workstations be installed as part of the "Install Kerberos Client" which is being run successfully?

I did do the install on the Ambari host and am now getting a different message would this be because the server is now on the Ambari host.

Ok so I updated the /etc/krb5.conf file to the same found on the KDC host and it seems to work now. I didn't see this step anywhere in the documentation and thought the wizard would install the clients.

Thanks a lot!
