Allen Wittenauer commented on HADOOP-13707: ------------------------------------------- /logs was specifically blocked way back when due to the sensitive nature of the content. Non-admin users shouldn't be looking at it at all and admin users have access from the shell. > If kerberos is enabled while HTTP SPNEGO is not configured, some links cannot > be accessed > ----------------------------------------------------------------------------------------- > > Key: HADOOP-13707 > URL: https://issues.apache.org/jira/browse/HADOOP-13707 > Project: Hadoop Common > Issue Type: Bug > Reporter: Yuanbo Liu > Labels: security > Attachments: HADOOP-13707.001.patch > > > 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.
