--------------------------------------------
[~ebadger], Planning to release 3.3.0.. Looks some jira's are pending on this
feature.. As some of jira's are already in 3.3.0,still you've plan to work on
rest of the jira's..?

> Key: YARN-9014
> URL: https://issues.apache.org/jira/browse/YARN-9014
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: Jason Darrell Lowe
> Assignee: Eric Badger
> Priority: Major
> Labels: Docker
> Attachments: OciSquashfsRuntime.v001.pdf,
> RuncContainerRuntime.v002.pdf

> This JIRA tracks a YARN container runtime that supports running containers in
> images built by Docker but the runtime does not use Docker directly, and
> Docker does not have to be installed on the nodes. The runtime leverages the
> [OCI runtime standard|https://github.com/opencontainers/runtime-spec] to
> launch containers, so an OCI-compliant runtime like {{runc}} is required.
> {{runc}} has the benefit of not requiring a daemon like {{dockerd}} to be
> running in order to launch/control containers.
> The layers comprising the Docker image are uploaded to HDFS as
> [squashfs|http://tldp.org/HOWTO/SquashFS-HOWTO/whatis.html] images, enabling
> the runtime to efficiently download and execute directly on the compressed
> layers. This saves image unpack time and space on the local disk. The image
> layers, like other entries in the YARN distributed cache, can be spread
> across the YARN local disks, increasing the available space for storing
> container images on each node.
> A design document will be posted shortly.
