> *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*
> # Stop calculating the Kerberos identities when Kerberos is not enabled
> # Protect access to the Kerberos configurations and set default values for
> needed configuration properties
