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.
