Allen Wittenauer commented on YARN-4595:
----------------------------------------
bq. If we're thinking of the same symlinks,
We're not. If I create an archive (tar, whatever) that contains symlinks and
those get unpacked as part of the task localization, IIRC I should be able to
access the target of the symlink if I mount the symlink in the container.
Using this method, I can access all sorts of fun things on the host from inside
the container.

> Mounting files or directories from the host is one way of passing
> configuration and other information into a docker container. We could allow
> the user to set a list of mounts in the environment of ContainerLaunchContext
> (e.g. /dir1:/targetdir1,/dir2:/targetdir2). These would be mounted read-only
> to the specified target locations.
