Subject [jira] [Commented] (YARN-7034) DefaultLinuxContainerRuntime and DockerLinuxContainerRuntime sends client environment variables to container-executor

Miklos Szegedi commented on YARN-7034:
--------------------------------------

Thank you, [~rkanter]. My concern is that I see little benefit. These environment variables
are for the container-executor and not the user container. I do not see any reason, why it
would be a good idea to change the container-executor environment variables. If you an point
out any example I could think of, I am happy to add the admin-env list.

> This behavior is unnecessary since there is nothing that is used from the environment
right now. One option is to whitelist these variables before passing them. Are there any known
use cases for this to justify?
