Zhankun Tang commented on YARN-3854:
------------------------------------
[~templedf], Thanks for the review.
My current plan is that we don't validate the credentials in this patch. The
credentials may be more suitable to be validated in YARN-5428 (the application
supplied config.json way).
I guess docker pull operation will fail fast if there is no credentials
prepared. Then the container is eventually failed.

> We need the ability to localize docker images when those images aren't
> already available locally. There are various approaches that could be used
> here with different trade-offs/issues : image archives on HDFS + docker load
> , docker pull during the localization phase or (automatic) docker pull
> during the run/launch phase.
> We also need the ability to clean-up old/stale, unused images.
