-------------------------------------
Summary: Make
CapacityScheduler#getOrCreateQueueFromPlacementContext more easy to comprehend
Key: YARN-10953
URL: https://issues.apache.org/jira/browse/YARN-10953
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Szilard Nemeth
1. Most of the method body is wrapped in an if-statement that checks if the
queue is null. We could negate this and return immediately if the queue !=
null, so we don't need a large if statement.
2. Similarly in that large if body, there's a check for
fallbackContext.hasParentQueue(). If it's true, we are having yet another large
if-body. We should also negate this condition and return immediately if it's
false.
