Zhankun Tang commented on YARN-3854:
------------------------------------
We need to delete the application scoped Docker image in local host once the
application finished. So this hint file is used for storing Docker images which
might be deleted at some point by DeletionService. I guess we should do it this
way but this is not the final version. Any possible options are welcomed.
> Add localization support for docker images

> 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.
