Wangda Tan commented on YARN-8882:
----------------------------------

[~tangzhankun], why rename "device-scheduler" to "device-mapping-manager"? :) I 
understand what it do is mapping devices to containers. But I would prefer to 
call it DeviceScheduler instead of DeviceMappingManager given name "scheduler" 
means booking, ordering, etc. 

> Phase 1 - Add a shared device mapping manager for device plugin to use

> Since a few devices uses FIFO policy to assign devices to the container, we 
> use a shared device manager to handle all types of devices.
