Brahma Reddy Battula commented on HADOOP-13707:

bq.I was using "Resume Progress" -> "Submit patch", but it didn't work
you've to re-upload the patch to run jenkins..
bq.It would be better if the dashboard contains something like "Rerun Jenkins" 
there is rebuild button and build with parameters.Only login users(with apache 
id) can trigger.

I Triggered the jenkins.

> In {{HttpServer2#hasAdministratorAccess}}, it uses 
> `hadoop.security.authorization` to detect whether HTTP is authenticated.
> It's not correct, because enabling Kerberos and HTTP SPNEGO are two steps. If 
> Kerberos is enabled while HTTP SPNEGO is not, some links cannot be accessed, 
> such as "/logs", and it will return error message as below:
> {quote}
> Problem accessing /logs/. Reason:
> User dr.who is unauthorized to access this page.
> {quote}
> We should make sure {{HttpServletRequest#getAuthType}} is not null before we 
> invoke {{HttpServer2#hasAdministratorAccess}}.
> {{getAuthType}} means to get the authorization scheme of this request
