Subru Krishnan updated YARN-2915:
---------------------------------
    Attachment: Yarn_federation_design_v1.pdf

Uploading a proposal of design based on offline design discussions within our 
team and with [~kasha], [~adhoot], [~vinodkv], [~acmurthy], [~tucu00] and more 
people (apologize if I missed anyone).  We validated the proposed design by 
developing a prototype and we have a basic end2end functioning system where we 
can stitch multiple YARN clusters into a unified federated cluster and run jobs 
that transparently span across all of them.

> This is an umbrella JIRA that proposes to scale out YARN to support large 
> clusters comprising of tens of thousands of nodes.   That is, rather than 
> limiting a YARN managed cluster to about 4k in size, the proposal is to 
> enable the YARN managed cluster to be elastically scalable.
