Arun Suresh updated YARN-7612:
------------------------------
Attachment: YARN-7612-v2.wip.patch
Updating with a v2 version of the patch.
* Rebased on latest version of YARN-7522
* Added an RejectedSchedulingRequest list in the AllocateResponse, which
notifies the Client/AM that a Scheduling Request could not be placed - Either
due to conflicting constraints (anti-affinily across nodes for 5 containers
when there are only 4 nodes), or due to some Scheduler rejection (request
exceeds userlimit / queue capacity / node size etc )
I will attaching a combined patch shortly to kick off jenkins
