> In response string of CapacityScheduler REST API, scheduler/schedulerInfo/health/operationsInfo have duplicate key 'entry' as a JSON object :
> {code}
> "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.
> After convert to List, The operationsInfo string will be:
> {code}
> "operationInfos":[
> {"operation":"last-allocation","nodeId":"N/A","containerId":"N/A","queue":"N/A"},
> {"operation":"last-release","nodeId":"N/A","containerId":"N/A","queue":"N/A"},
> {"operation":"last-preemption","nodeId":"N/A","containerId":"N/A","queue":"N/A"},
> {"operation":"last-reservation","nodeId":"N/A","containerId":"N/A","queue":"N/A"}
> ]
> {code}
