    Affects Versions: 2.8.0
            Reporter: Robert Kanter

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.

Here are the URLs:
- http://HOST:8088/static/
- http://HOST:19888/static/
- http://HOST:8042/static/
