Eric Yang commented on YARN-7960:
---------------------------------
[~ebadger] You are right. Selinux presence is not a good indicator if the
option should be enabled or not. No_new_privileges can work with selinux after
CentOS 7.5. Config knob for this feature is the better choice.
> Add no-new-privileges flag to docker run

> Minimally, this should be used for unprivileged containers. It's a cheap way
> to add an extra layer of security to the docker model. For privileged
> containers, it might be appropriate to omit this flag
