> 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.
