--------------------------------
Hi, [~sunilg]. Thank you for looking into the issue.

It will break compatibility to previous version since REST response will be
different from map to list, correct?

Correct. The response will be different, but I think the effect would be small,
since this field is only used in REST and the previous version can not be used
with incorrect format. Thoughts?
> 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
> Attachments: YARN-6257.001.patch

>
> 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.
