Jim Brennan commented on YARN-9564:
-----------------------------------

Based on my testing with the latest patches for YARN-9561, YARN-9562, and this 
patch, I am +1 (non-binding) on patch 004.  I was able to use docker2squash.py 
to pull a docker image, squash it, and push the layers to my local hdfs.  I was 
then able to run some test jobs using the runc container runtime.

> The new runc runtime uses docker images that are converted into multiple 
> squashfs images. Each layer of the docker image will get its own squashfs 
> image. We need a tool to help automate the creation of these squashfs images 
> when all we have is a docker image
