Review request for Ambari and Robert Levas.
Bugs: AMBARI-11647
https://issues.apache.org/jira/browse/AMBARI-11647
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

[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.
