Wangda Tan commented on YARN-2885:

bq. ... That said, I am not sure if it is required to create a wrapper at this 
point for the AM protocol.
As suggested by [~asuresh], 
bq. Have an Distributed Scheduler AM Service running on the RM if DS is 
enabled. This will implement the new protocol (it will delegate all the 
AMProtocol stuff to the AMService and will handle DistScheduler specific stuff)
Do you think if it's a good idea?

> We propose to add a Local ResourceManager (LocalRM) to the NM in order to 
> support distributed scheduling decisions. 
> Architecturally we leverage the RMProxy, introduced in YARN-2884. 
> The LocalRM makes distributed decisions for queuable containers requests. 
> Guaranteed-start requests are still handled by the central RM.
