> *Cause*
> This is caused in the {{org.apache.ambari.server.controller.internal.HostKerberosIdentityResourceProvider}}
when the relevant host is the host where the Ambari server is installed and Kerberos is *_not_*
enabled.  
> When querying information about a host via {{GET /api/v1/clusters/CLUSTERNAME/hosts/HOSTNAME}},
the relevant Kerberos identities for that host are generated.  This happens whether Kerberos
is enabled or not.  If the host is the host where the Ambari server is installed, than code
is invoked to calculate the Ambari server's Kerberos identity.  In this code, the Kerberos-specific
configurations are retrieved. If Kerberos is not enabled, these configurations will not be
available and thus the error, "The 'krb5-conf' configuration is not available", is encountered.

> *Solution*
> There are several possible solutions to this:
> # Stop calculating the Kerberos identities when Kerberos is not enabled
> # Protect access to the Kerberos configurations and set default values for needed configuration
properties
> If we stop calculating the Kerberos identities when Kerberos is not enabled, then there
will be no way to query Ambari for what Kerberos identities are expected once the cluster
is Kerberized.
> If we provide default values for the missing Kerberos properties, we need to set a default
for {{kerberos-env/create_ambari_principal}}.  The default value for this in the stack definition
is {{true}}.
> The best solution appears to be #2 and set a default value for {{kerberos-env/create_ambari_principal}}
to be {{true}}.
