Yuanbo Liu commented on HADOOP-14060:
-------------------------------------
The filter chain of {{/logs}} is
{code}
NoCacheFilter->safety->static_user_filter
{code}
while the filter chain of {{/jmx}} is
{code}
NoCacheFilter->safety->static_user_filter->authFilter->MDCFilter
{code}
The authFilter requires kerberos authentication, that's why the responses of
{{/jmx}} and {{/logs}} are different.
> KMS /logs servlet should have access control

> Key: HADOOP-14060
> URL: https://issues.apache.org/jira/browse/HADOOP-14060
> Project: Hadoop Common
> Issue Type: Bug
> Components: kms
> Affects Versions: 3.0.0-alpha3
> Reporter: John Zhuge
> Assignee: John Zhuge
>
> HADOOP-14047 makes KMS call {{HttpServer2#setACL}}. Access control works fine
> for /conf, /jmx, /logLevel, and /stacks, but not for /logs.
> The code in {{AdminAuthorizedServlet#doGet}} for /logs and
> {{ConfServlet#doGet}} for /conf are quite similar. This makes me believe that
> /logs should subject to the same access control as intended by the original
> developer.
> IMHO this could either be my misconfiguration or there is a bug somewhere in
> {{HttpServer2}}.
