Robert Kanter updated HADOOP-12584:
-----------------------------------
    Attachment: HADOOP-12584.001..patch

Simple fix sets {{org.eclipse.jetty.servlet.Default.dirAllowed}} to {{false}}.  I verified
that with the patch you can't browse the files anymore.

> 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.
