Robert Levas created AMBARI-9785:
------------------------------------

             Summary: Root user has spnego (HTTP) kerberos ticket set after Kerberos is enabled, root should have no ticket.
                 Key: AMBARI-9785
                 URL: https://issues.apache.org/jira/browse/AMBARI-9785
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: 2.0.0
            Reporter: Robert Levas
            Assignee: Robert Levas
            Priority: Blocker
             Fix For: 2.0.0


After enabling Kerberos, the root user has the spnego user set for it 

{code}
[root@c6501 ~]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: HTTP/c6501.ambari.apache.org@EXAMPLE.COM

Valid starting     Expires            Service principal
02/18/15 22:14:51  02/19/15 22:14:51  krbtgt/EXAMPLE.COM@EXAMPLE.COM
	renew until 02/18/15 22:14:51
{code}

It appears that the issue is related to the agent-side scheduler and/or some job that is scheduled to run periodically. Apparently some job is kinit-ing with the SPNEGO identity as the running user (root in this case) without changing the ticket cache. Thus whenever the job runs the root user's ticket cache gets changed to contain the SPNEGO identity's ticket.
