Eric Badger resolved YARN-8241.
-------------------------------
Resolution: Won't Fix
We do not plan to support running containers in which a user lookup cannot be
performed. This is to be considered a base requirement for a container to run.
Some sort of user lookup mechanism such as nscd, sssd, /etc/passwd, or
something else needs to be implemented so that the UID:GID pair can be linked
to a user and group
> MRAppMaster fails when using UID:GID pair within docker container

> the MRAppMaster fails for docker containers if there is no additional user
> lookup strategy (e.g. bind-mounting /var/run/nscd or /etc/passwd). We need a
> better solution so that users can still run even if they are not known inside
> of the container by name
