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?
Thanks
