Yes, I can access only the whitelist endpoints.
my-jobhistoryserver configs:
```xml
<property name="hadoop.http.authentication.kerberos.endpoint.whitelist"
value="/isActive,/jmx,/prom"/>
<property name="hadoop.http.authentication.kerberos.keytab"
value="/path/to/spnego.keytab"/>
<property name="hadoop.http.authentication.kerberos.principal"
value="HTTP/_HOST@MY_REALM"/>
<property name="hadoop.http.authentication.type" value="kerberos"/>
<property name="hadoop.http.filter.initializers"
value="org.apache.hadoop.security.AuthenticationFilterInitializer,org.apache.hadoop.http.lib.StaticUserWebFilter,org.apache.hadoop.security.HttpCrossOriginFilterInitializer"/>
```

> Thanks to HADOOP-16527, we can add a whitelist of endpoints to skip Kerberos
> authentication such as {{/isActive}}, {{/jmx}}, {{/prom}}.
> However, I found that ResourceManager and Job History Server doesn't repect
> {{hadoop.http.authentication.kerberos.endpoint.whitelist}}.
> To workaround this issue for ResourceManager, set
> {{yarn.resourcemanager.webapp.delegation-token-auth-filter.enabled=true}} in
> yarn-site.xml.
> However, there is no workaround for Job History Server.
> This bug is caused by {{HttpServer2#initSpnego}} call without proper
> configurations which starts with "{{hadoop.http.authentication.}}".
> I will make a PR soon.
