Subject [jira] [Commented] (YARN-3854) Add localization support for docker images
Date Fri, 22 Jul 2016 01:21:20 GMT

Zhankun Tang commented on YARN-3854:
------------------------------------

Yes. Explicit "docker pull" have the benifit over implicitly that we can know this "pull"
process is not successful and we can kill it. If delegate this to the "docker run" implicitly
we have no way to distingush why we failed to launch the container.
