------------------------------------------------------------
Thanks for the patch, [~shaneku...@gmail.com]. One question:
I remember "docker login" will store the credentials in ~/.docker/config.json
by default. Will this patch eliminate the need of "docker login"? Or should the
administrator store credentials in the config.json file manually?

> The docker client allows for specifying a configuration directory that
> contains the docker client's configuration. It is common to store "docker
> login" credentials in this config, to avoid the need to docker login on each
> cluster member.
> By default the docker client config is $HOME/.docker/config.json on Linux.
> However, this does not work with the current container executor user
> switching and it may also be desirable to centralize this configuration
> beyond the single user's home directory.
> Note that the command line arg is for the configuration directory NOT the
> configuration file.
> This change will be needed to allow YARN to automatically pull images at
> localization time or within container executor.
