    Description

      Currently, the "top level" log and local directories are mounted inside docker containers (see below for an example). This is not restrictive enough - we need to ensure that only container specific directories are mounted.

      /dev/sda4 on /grid/0/hadoop/yarn/local/usercache/root/appcache/application_1451931954322_0020/container_e50_1451931954322_0020_01_000002 type ext4 (rw,relatime,data=ordered)
