Miklos Szegedi commented on YARN-7066:
--------------------------------------

[~eyang], is not this a security issue? What protects against mounting any directory from
the client on the node and modifying as root?

> Yarnfile describes environment, docker image, and configuration template for launching
docker containers in YARN.  It would be nice to have ability to specify the volumes to mount.
 This can be used in combination to AMBARI-21748 to mount HDFS as data directories to docker
containers.
