------------------------------------------
Mostly looks good.
Can you add the file license header to hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/webapp/dao/CapacitySchedulerQueueInfoList.java

> When the capacity scheduler is configured for more than two levels of queues, the web services API returns incorrect JSON for the subQueues field of some parent queues. The "subQueues" field for parent queues should always be an array, but sometimes the field appears multiple times for a queue and as what looks like a CapacityQueueInfo object instead of an array. Besides the sometimes-an-array-sometimes-not problem, parsing the result into a JSON object causes all but the last "subQueues" field to be discarded since they are overwritten by subsequent fields with the same name.
