Abin Shahab commented on YARN-1964:
-----------------------------------
Sid, thanks for looking at it.
The docker image is sequenceiq/hadoop-docker:2.4.0 with all the HADOOP_*
environments exposed. I would not even upload our image if sequenceiq's image
exposed all the environment variables.
So I'm not sure why it takes so much time. I'd say try comparing it with the
download time of sequenceiq/hadoop-docker:2.4.0(on a different machine,
otherwise you'll get the tag from the docker cache).
I'll try to rebase the patch soon.

> Docker (https://www.docker.io/) is, increasingly, a very popular container
> technology.
> In context of YARN, the support for Docker will provide a very elegant
> solution to allow applications to *package* their software into a Docker
> container (entire Linux file system incl. custom versions of perl, python
> etc.) and use it as a blueprint to launch all their YARN containers with
> requisite software environment. This provides both consistency (all YARN
> containers will have the same software environment) and isolation (no
> interference with whatever is installed on the physical machine).
