> Introduction 
> 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. This has been resolved
in YARN-4595
> 2.Problem Definition
> Bug mounting arbitrary volumes into a Docker container can be a security risk.
> 3.Possible solutions
> one approach to provide safe mounts is to allow the cluster administrator to configure
a set of parent directories as white list mounting directories.
>  Add a property named yarn.nodemanager.volume-mounts.white-list, when container executor
do mount checking, only the allowed directories or sub-directories can be mounted.
