> YARN-6623 added support in container-executor for admin supplied Docker volume whitelists.
This allows controlling which host directories can be mounted into Docker containers launched
by YARN. A read-only and read-write whitelist was added. We now need the ability for users
to supply the mounts they require for their application, which will be validated against the
admin whitelist in container-executor.
