--------------------------------------------------------------
[~eyang] thanks for the updated patch. I'm still confused as to what this is
providing over YARN-5534. Both support the user supplying mounts via an
environment variable, which then gets added to the {{docker run}} command. The
only difference for that piece is the format of the user supplied environment
variable, but YARN-5534 goes a step further to attempt to validate the mount is
also in the white list. I reread your comment about why you feel the approach
used by this patch is superior, but I'm not following what you mean.

> Yarnfile describes environment, docker image, and configuration template for
> launching docker containers in YARN. It would be nice to have ability to
