Daniel Templeton commented on YARN-3854:
----------------------------------------
Thanks, [~tangzhankun]. I just took a look through the proposal, and it looks
good. In the implementation section, you mention that you're solution for
dealing with credentials is to assume that proper credentials exist. Are you
planning to validate or enforce that assumption? If not, the implementation
will have to deal with what happens when the credentials don't exist or aren't
correct.

> 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.
