> Currently ApplicationSubmissionContext API supports specifying a node label expression for the AM resource request. It would be beneficial to have the ability to specify Placement Constraints as well for the AM resource request. We have a requirement to constrain AM containers on certain nodes e.g. AM containers not on preemptible/spot cloud instances. It looks like node attributes would fit our use case well. However, we currently don't have the ability to specify this in the API for AM resource requests.
