Sunil Govindan commented on YARN-8015:
--------------------------------------
Thanks for the patch [~cheersyang]
Some quick questions:
# To support affinity for node partition, i think current patch supports to
fetch the partition from incoming expression. Setting in targetNodePartition is
enough?
# I just saw that {{if (!(ac instanceof
PlacementConstraint.SingleConstraint))}} is removed. But this check is needed,
correct?
> Complete placement constraint support for Capacity Scheduler

> AppPlacementAllocator currently only supports intra-app anti-affinity
> placement constraints, once YARN-8002 and YARN-8013 are resolved, it needs to
> support inter-app constraints too. Also, this may require some refactoring on
> the existing code logic. Use this JIRA to track.
