Chi Heng updated YARN-10867:
----------------------------
Description: In some scenarios, like mounting a FUSE in docker,user needs
to map a custom device (eg. /dev/fuse) into docker container.I notice that an
adddevice method is defined in [

,I suppose that an ENV or config property should to be exposed to user to call
this method (was: In some scenarios, like mounting a FUSE in docker,user needs
