Review request for Ambari and Robert Levas.


Repository: ambari


Description
-------

When enabling Kerberos on a non-root Ambari 2.0.0-151 setup, the Check Kerberos 
step fails during the Test Kerberos Client task.

The problem in the tasks stderr is:

Fail: Execution of '/usr/bin/kinit -c 
/var/lib/ambari-agent/data/tmp/kerberos_service_check_cc_30399f1839f2d5ac0ada0c280b95657e
 -kt /etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab 
[email protected]' returned 1. kinit: Permission denied while 
getting initial credentials


When capturing that keytab with 'cp -a' and trying to use it, I fail to 
authenticate:


[root@revo4 ~]# ls -l 
/etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab 
-rw-r-----. 1 ambari-qa hadoop 358 Jun  1 15:22

[root@revo4 ~]# klist -ket

[root@revo4 ~]# kinit -kt 
/etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab 
[email protected]
kinit: Client not found in Kerberos database while getting initial credentials

I validated that this kinit call is not run through sudo as there are no 
entries in /var/log/secure denying the action, and there are no instances in 
which ambari-sudo.sh is being called in regards to this command that I could 
find.

So, I need help in identifying why this is happening during the Check Kerberos 
step, and why the captured keytab isn't usable.
