------------------------------

             Summary: CapacityScheduler REST API produces incorrect JSON - JSON object operationsInfo contains deplicate key
                 Key: YARN-6257
                 URL: https://issues.apache.org/jira/browse/YARN-6257
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
    Affects Versions: 2.8.1
            Reporter: Tao Yang
            Assignee: Tao Yang
            Priority: Minor


In response string of CapacityScheduler REST API, scheduler/schedulerInfo/health/operationsInfo have duplicate key 'entry' as a JSON object :
{code:json}
"operationsInfo":{
  "entry":{"key":"last-preemption","value":{"nodeId":"N/A","containerId":"N/A","queue":"N/A"}},
  "entry":{"key":"last-reservation","value":{"nodeId":"N/A","containerId":"N/A","queue":"N/A"}},
  "entry":{"key":"last-allocation","value":{"nodeId":"N/A","containerId":"N/A","queue":"N/A"}},
  "entry":{"key":"last-release","value":{"nodeId":"N/A","containerId":"N/A","queue":"N/A"}}
}
{code}

To solve this problem, I suppose the type of operationsInfo field in CapacitySchedulerHealthInfo class should be converted from Map to List.
