> Reserved Containers are not allocated from the available space of other nodes 
> in CandidateNodeSet in MultiNodePlacement. 
> *Repro:*
> 1. MultiNode Placement Enabled.
> 2. Two nodes h1 and h2 with 8GB
> 3. Submit app1 AM (5GB) which gets placed in h1 and app2 AM (5GB) which gets 
> placed in h2.
> 4. Submit app3 AM which is reserved in h1
> 5. Kill app2 which frees space in h2.
> 6. app3 AM never gets ALLOCATED
> RM logs shows YARN-8127 fix rejecting the allocation proposal for app3 AM on 
> h2 as it expects the assignment to be on same node where reservation has 
> happened.
