> Kerberos identities are not removed for components that exist on multiple
> hosts.
> For example, if {{SERVICEA/COMPONENT1}} is installed on {{HOST1}} and
> {{HOST2}} and its relevant principal is named {{component1/\_HOST@REALM}},
> then the host-specific principal and keytab file will not be removed if
> {{SERVICEA/COMPONENT1}} is removed from {{HOST1}} *_or_* {{HOST2}}. It will
> be removed if {{SERVICEA/COMPONENT1}} is removed from {{HOST1}} *_and_*
> {{HOST2}}.
> This is due to the incorrect principal name comparison when determine whether
> a Kerberos identity is to be removed or not. See
> {{org.apache.ambari.server.controller.utilities.UsedIdentities#contains}}.
