Weiwei Yang commented on YARN-8007: ----------------------------------- Hi [~yangjiandan] Thanks for initiating this, it makes a lot of sense to help test scheduler perf with placement constraints, There are a few general comments to your patch # Instead of using {{SourceTags}} abstraction, lets follow the public API in scheduling request, which is to provide a Set<String> of source tags and a PlacementConstraint. I think you will need 2 configs, allocation_tags: foo,bar placement_constraint: notin,node,foo this way we can honor number of tasks in the config. # I don't think we need to add placement constraint field in ContainerSimulator, a placement constraint is request level, not container level. # Have you tried to run this and how this works out?
