Karthik Kambatla commented on YARN-4888:
----------------------------------------

I like the idea of SchedulerKey. It also opens it upto a custom SchedulerKey 
implementation in the future.

How easy/hard would it be to do this as two patches - one that switches the 
current code to use SchedulerKey and another to add allocation_request_id?
