-----------------------------------------
/cc [~zyluo], [~vvasudev]
As discussed in YARN-5360, I don't think its a good idea to mount /etc/passwd
into a container without any way to disable it. At a minimum, we should add a
(cluster-wide?) mechanism to control this (and it should be disabled by
default, IMO).

> Current LCE (DockerLinuxContainerRuntime) is mounting /etc/passwd to the
> container. But it seems to use wrong file name "/etc/password" for container.
> {panel}
> .addMountLocation("/etc/passwd", "/etc/password:ro");
> {panel}
> This causes LCE failed to launch the Docker container if the Docker images
> don't create the same user name and UID in it.
