> 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.
