Jaimin D Jetly commented on AMBARI-8166:
----------------------------------------

We need to test that the KDC host:port are reachable from all hosts in the cluster as part of this task. It will be a pre-check before installing kerberos clients on all hosts and configuring kerberos client related files (krb5.conf). 

Authentication of an identity (smokeuser identity) will be done after kerberos service (comprises of only kerberos client components)  is installed as part of kerberos service check command (smoke test for kerberos service). This will be a separate task.

> There needs to be a way, given the details about a KDC to verify that Ambari and (optionally) the nodes in the existing cluster can connect to it. 
> From the cluster hosts, this test should test that the address and port combinations are reachable. 
> From the Ambari server, this test should make sure the administrator credentials allow at least read access to the KDC.
> As an example of a similar action, see how Oozie does this for DB check pre install.
