Eric Yang commented on YARN-8643:
---------------------------------
Subtask can not have more subtask. Therefore, I opened YARN-9228 as the
umbrella JIRA to cover all the research and development subtasks for hosting
docker images on HDFS.

> This JIRA is forking an idea proposed in YARN-3854 to manage trusted docker
> images on HDFS. YARN-3854 is going to focus on rearranging the node manager
> and container-executor logic to download docker image during file
> localization phase for better error handling and reporting. The new proposal
> is to create a docker container which host Docker registry and NFS gateway,
> and configure docker images to store on HDFS. The docker container can run
> in YARN framework to serve as privileged or trusted registries.
> HDFS_Docker_registry_design.png describes the components required to create a
> docker image that can store docker images on HDFS.
> Deploy_HDFS_Docker_registry_workflow.png describes the operation to perform
> to setup a trusted docker registry that write to HDFS.
