Subject [jira] [Created] (AMBARI-9985) Maintenance Mode Hosts do not get keytabs
Date Mon, 09 Mar 2015 18:17:38 GMT
Robert Levas created AMBARI-9985:
------------------------------------

             Summary: Maintenance Mode Hosts do not get keytabs
                 Key: AMBARI-9985
                 URL: https://issues.apache.org/jira/browse/AMBARI-9985
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Robert Levas
            Assignee: Robert Levas
            Priority: Critical
             Fix For: 2.0.0


A downed host behaves a little differently then a host that is up and in a maintenance state.
 

It appears that where a downed host is not included in steps to install the Kerberos client
nor is it included when choosing a host to run the service check on. 

However a host that is up and in maintenance mode is not included in steps to install the
Kerberos client, but may be selected as the host to run the service check on. Resulting in
this error:

{code}
2015-03-04 20:58:03,164 - Error while executing command 'service_check':
Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py",
line 208, in execute
    method(env)
  File "/var/lib/ambari-agent/cache/common-services/KERBEROS/1.10.3-10/package/scripts/service_check.py",
line 58, in service_check
    raise Fail(err_msg)
Fail: Failed to execute kinit test due to principal or keytab not found or available
{code}

The error is correct in that the keytab has not been distributed to it, this is because the
Kerberos Client has not been installed on it.
