> 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).
