Eric Yang resolved YARN-7992.
-----------------------------
Resolution: Not A Problem
Launch_container.sh is copied to usercache with proper permission. That copy
is the one used by docker container launcher. Therefore the intermediate copy
in nmPrivate with incorrect permission is not an issue.
> launch_container.sh has the wrong file permission
