Eric Yang commented on YARN-8342:
---------------------------------
[~vinodkv] Launch command was dropped in YARN-7516 due to concerns of shell
expansion to cause the commands to run as root user via popen. With YARN-7654
changes to use execvp, this concern has been nullified. It is safe to preserve
launch command even for untrusted images.

> Using docker image from a non-privileged registry, the launch_command is not
> honored

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Wangda Tan
> Priority: Critical
> Labels: Docker
>
> During test of the Docker feature, I found that if a container comes from
> non-privileged docker registry, the specified launch command will be ignored.
> Container will success without any log, which is very confusing to end users.
> And this behavior is inconsistent to containers from privileged docker
> registries.
