Yufei Gu commented on YARN-9298:
--------------------------------
[~wilfreds], thanks for the patch. Looks really good! Just some nits:
1. There are unused imports in class FairQueuePlacementUtils and class
PlacementRule
2. {{private PlacementRule parentRule = null;}}, no need set it to null as a
class member since the default is null.
3. {{protected boolean createQueue = false;}}, I suggest to remove the
initialization or set it to true since it will be set to true by default anyway.
