[jira] [Created] (YARN-6429) Revisit implementation of LocalitySchedulingPlacementSet to avoid invoke methods of AppSchedulingInfo

Wangda Tan created YARN-6429:
--------------------------------

             Summary: Revisit implementation of LocalitySchedulingPlacementSet to avoid invoke methods of AppSchedulingInfo
                 Key: YARN-6429
                 URL: https://issues.apache.org/jira/browse/YARN-6429
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
            Reporter: Wangda Tan
            Assignee: Wangda Tan


An example is, LocalitySchedulingPlacementSet#decrementOutstanding: it calls appSchedulingInfo directly, which could potentially cause trouble since it tries to modify parent from child. Is it possible to move this logic to AppSchedulingInfo#allocate.

Need to check other methods as well.
