Subject [jira] [Reopened] (HADOOP-12584) Disable browsing the static directory in HttpServer2

Steve Loughran reopened HADOOP-12584:
-------------------------------------

I'm re-opening this briefly until a patch including the YARN-4379 diff is merged in, with
a test run against YARN too. Sorry, but I'm getting fed up with the fact that hadoop jenkins
builds are so unreliable that them and patch test runs are essentially meaningless

> We found a minor security issue with the Yarn Web UIs (or anything using {{HttpServer2}}.
 Currently, you can list the contents of the {{/static}} directory for the RM, NM, and JHS.
 This isn't a huge deal, but there are some ways to abuse this to get access to files on the
host, though it would be pretty difficult.  It's also good practice to disable directory listing
on web apps.
