Sunil G updated YARN-7494:
--------------------------
Attachment: YARN-7494.v0.patch
v0 patch. cc/[~leftnoteasy]
Few assumptions.
* LocalityAppPlacementAllocator was hardcoded earlier in AppSchedulingInfo. Now
this will be chosen based on application submission context.
* Introduced PartitionBasedCandidateNodeSet which will store nodes per
partition and implements {{getPreferredNodeIterator}} to return a set of nodes
sorted based on its utilization.
> Add muti node lookup support for better placement
