Apache Hadoop YARN is a modern resource-management platform that handles resource scheduling, isolation and multi-tenancy for a variety of data processing engines that can co-exist and share a single data-center in a cost-effective manner.
In the first half of the talk, we are going to give a brief look into some of the big efforts cooking in the Apache Hadoop YARN community.
We will then dig deeper into one of the efforts - supporting Docker runtime in YARN. Docker is an application container engine that enables developers and sysadmins to build, deploy and run containerized applications. In this half, we'll discuss container runtimes in YARN, with a focus on using the DockerContainerRuntime to run various docker applications under YARN. Support for container runtimes (including the docker container runtime) was recently added to the Linux Container Executor (YARN-3611 and its sub-tasks). We’ll walk through various aspects of running docker containers under YARN - resource isolation, some security aspects (for example container capabilities, privileged containers, user namespaces) and other work in progress features like image localization and support for different networking modes.
