Varun Vasudev commented on YARN-3854:
-------------------------------------

[~tangzhankun] - the general approach looks ok to me. Do you want to go ahead and file tickets
for the tasks and start the implementation?

> 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.
