Eric Badger commented on YARN-3854:
-----------------------------------
I like that proposal. We'll need to make sure that there aren't any weird race
conditions with containers being stopped in the YARN sense, but not the docker
sense. But other than that, I think this gives us a better idea of the state of
the node. Makes me worry a lot less about force removing 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.
