Arun Suresh updated YARN-2885:
    Attachment: YARN-2885-yarn-2877.001.patch

Uploading a preliminary version of the patch..

# This depends on YARN-2882. Will upload a combined patch shortly
# This patch introduces a Distributed Scheduling Request Interceptor using the 
AMRMProxy framework introduced in YARN-2884. The interceptor is set at the head 
of the pipeline if Distributed Scheduling is enabled.
# An AM requiring Distributed scheduling can mark certain resource request asks 
with Execution Type QUEUEABLE. This is currently used just a means of 
partitioning the asks. The actual QUEUE-ing at the target NM will be tackled as 
part of YARN-2883
# Will be adding more test cases shortly

> Create AMRMProxy request interceptor for distributed scheduling decisions for 
> queueable containers

> 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.
