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 /etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab [root@revo4 ~]# klist -ket /etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab Keytab name: FILE:/etc/security/keytabs/kerberos.service_check.pfrlxjlh.keytab KVNO Timestamp Principal ---- ----------------- -------------------------------------------------------- 1 06/01/15 15:22:01 [email protected] (arcfour-hmac) 1 06/01/15 15:22:01 [email protected] (aes256-cts-hmac-sha1-96) 1 06/01/15 15:22:01 [email protected] (aes128-cts-hmac-sha1-96) 1 06/01/15 15:22:01 [email protected] (des-cbc-md5) 1 06/01/15 15:22:01 [email protected] (des3-cbc-sha1) [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.

Install cluster with ambari-agent 2. Kerberize it also mvn clean test Thanks, Andrew Onischuk
