Abin Shahab commented on YARN-1964:

We have decided to create an umbrella issue to cover the integration between 
YARN and Docker(YARN-2466). 
This task(YARN-1964) has the following scope:
1) Launch docker containers from YARN with net=host mode. This will allow the 
container to take on the host's network, and therefore the YARN administrators 
will not need to set up special networking for docker.
2) Allow users to provide docker images through the job configuration.
3) Setup and user guides.

The rest(secure hadoop, advanced networking) will be handled in other issues 
under YARN-2466. 
Please add your feedback to this plan on this jira.

> 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).
