> In some clusters of ours, we are seeing "Used Resource","Used
> Capacity","Absolute Used Capacity" and "Num Container" is positive or
> negative when the queue is absolutely idle(no RUNNING, no NEW apps...).In
> extreme cases, apps couldn't be submitted to the queue that is actually idle
> but the "Used Resource" is far more than zero, just like "Container Leak".
> Firstly,I found that "Used Resource","Used Capacity" and "Absolute Used
> Capacity" use the "Used" value of ResourceUsage kept by AbstractCSQueue, and
> "Num Container" use the "numContainer" value kept by LeafQueue.And
> AbstractCSQueue#allocateResource and AbstractCSQueue#releaseResource will
> change the state value of "numContainer" and "Used". Secondly, by comparing
> the values numContainer and ResourceUsageByLabel and QueueMetrics
> changed(#allocateContainer and #releaseContainer) logic of applications with
> and without "movetoqueue",i found that moving the reservedContainers didn't
> modify the "numContainer" value in AbstractCSQueue and "used" value in
> ResourceUsage when the application was moved from a queue to another queue.
> The metric values changed logic of reservedContainers are allocated,
> and moved from $FROM queue to $TO queue, and released.The degree of increase
> and decrease is not conservative, the Resource allocated from $FROM queue and
> release to $TO queue.
> ||move reversedContainer||allocate||movetoqueue||release||
