> Docker image with latest tag can run in YARN cluster without any validation in node managers.
If a image with latest tag is changed during containers launch. It might produce inconsistent
results between nodes. This is surfaced toward end of development for YARN-9184 to keep docker
image consistent within a job. One of the ideas to keep :latest tag consistent for a job,
is to use docker image command to figure out the image id and use image id to propagate to
rest of the container requests. There are some challenges to overcome:
>  # The latest tag does not exist on the node where first container starts. The first
container will need to download the latest image, and find image ID. This can introduce lag
time for other containers to start.
>  # If image id is used to start other container, container-executor may have problems
to check if the image is coming from a trusted source. Both image name and ID must be supply
through .cmd file to container-executor. However, hacker can supply incorrect image id and
defeat container-executor security checks.
> If we can over come those challenges, it maybe possible to keep docker image consistent
with one application.
