-------------------------------------

             Summary: Hive Metastore did not start when Kerberized
                 Key: AMBARI-13133
                 URL: https://issues.apache.org/jira/browse/AMBARI-13133
             Project: Ambari
          Issue Type: Bug
            Reporter: Robert Levas
            Priority: Critical


When starting up HiveMetastore under a Kerberized cluster, the following error occurs:
{code}
resource_management.core.exceptions.Fail: Execution of '/usr/bin/kinit -kt /etc/security/keytabs/hive.service.keytab hive/host1.company.com@REALM; ' returned 1. kinit: Keytab contains no suitable keys for hive/host1.company.com@REALM while getting initial credentials
{code}

This happens when Hive Metastore and HiveServer2 principals are set up distinct from each other.
Hive Metastore is not using hive.metastore.kerberos.principal, but instead it uses hive.server2.authentication.kerberos.principal

Also, the following references hive_conf_dir:
https://github.com/apache/ambari/blob/release-2.1.1/ambari-server/src/main/resources/common-services/HIVE/0.12.0.2.0/package/scripts/hive_metastore.py#L119-L120

In HDP2.3+ the following file content becomes UNSECURED
/var/lib/ambari-agent/data/structured-out-status.json

We need to either reference hive_server_conf_dir or set hive_conf_dir as hive_server_conf_dir somewhere:
https://github.com/apache/ambari/blob/release-2.1.1/ambari-server/src/main/resources/common-services/HIVE/0.12.0.2.0/package/scripts/status_params.py#L90-L101

*Solution*
Since a kinit call here is unnecessary and the relevant configuration files are being created properly.  Simply removing the kinit call (and related variabled) will fix the kinit failure issue.

For the hive_conf_dir issue, setting {{hive_conf_dir = hive_server_conf_dir}} in status_params.py, solves the issue.
