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.
