Eric Badger commented on YARN-6623:
-----------------------------------

Given that docker is alpha in 2.8.2, I agree with [~vinodkv] that we should not backport this to 2.8.2, as it makes significant changes to the container-executor. Nobody should even attempt seriously running docker on 2.8.2 without backporting most, if not everything that's in 2.9 and doing a large security review over their configurations and setup. So, in my mind, some docker code may be "in" 2.8.2, but it really isn't supported at all until 2.9+. The only reason I can think of to put this in 2.8.2 would be to get the changes to container-executor, but it's not obvious to me why we would need those.

> Currently, launching privileged containers is controlled by the NM. We should add a flag to the container-executor.cfg allowing admins to disable launching privileged containers at the container-executor level.
