Summary: Expose canAssign method in the PlacementConstraintManager
Key: YARN-7682
URL: https://issues.apache.org/jira/browse/YARN-7682
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Arun Suresh
Assignee: Panagiotis Garefalakis
As per discussion in YARN-7613. Lets expose {{canAssign}} method in the
PlacementConstraintManager that takes a sourceTags, applicationId,
SchedulerNode and AllocationTagsManager and returns true if constraints are not
violated by placing the container on the node.
I prefer not passing in the SchedulingRequest, since it can have > 1
numAllocations. We want this api to be called for single allocations.
