Jim Brennan commented on YARN-9391:
-----------------------------------
[~ebadger] you are correct. It doesn't look like we explicitly add PATH to the
container environment unless is is specified in {{yarn.nodemanager.admin-env}}
or, as you say, if it is specified in {{yarn.nodemanager.env-whitelist}}.
[~eyang] do you know where the PATH variable is coming from in this case?

> This is observed from using Apache NiFi docker image. It makes assumption
> that PATH variable contains /bin to reference to system utility. Where host
> YARN environment PATH variable is default to leaked into container by
> accident and not containing /bin path (default configuration). In general,
> it seems like node manager should block PATH variable from leaking into
> container. Not sure if there is a valid use case that host PATH variable
> must leak into container from docker point of view. From Hadoop point of
> view, if container is merely a chroot, and container is a mirror image of
> host worker dir. It is good to keep host PATH variable the same.
> Maybe we want to be more specific that block PATH variable to leak into
> Docker container, if it is using ENTRYPOINT only?
