> Disabling Kerberos after enabled during Blueprint install fails with missing
> data directory error.
> !image-2017-12-11-15-12-21-492.png|thumbnail!
> This is caused by an invalid security state set for the installed components
> since the appropriate state is not set while enabling Kerberos during the
> installation process:
> {noformat}
> ambari=> select * from hostcomponentstate;
> id | cluster_id | component_name | version | current_state | host_id
> | service_name | upgrade_state | security_state
> ----+------------+------------------+--------------+---------------+---------+--------------+---------------+----------------
> 1 | 2 | KERBEROS_CLIENT | UNKNOWN | INSTALLED | 1
> | KERBEROS | NONE | UNSECURED
> 2 | 2 | ZOOKEEPER_CLIENT | 2.5.0.0-1245 | INSTALLED | 1
> | ZOOKEEPER | NONE | UNSECURED
> 3 | 2 | ZOOKEEPER_SERVER | 2.5.0.0-1245 | STARTED | 1
> | ZOOKEEPER | NONE | UNSECURED
> {noformat}
> The expected state for each component is {{SECURED}}, not {{UNSECURED}}.
> Because of this, Ambari _thinks_ there is no work to be done, causing this
> issue.
