> In existing Capacity Scheduler, it can limit max applications running within a queue. The config is yarn.scheduler.capacity.maximum-am-resource-percent, but actually, it is used as "ratio", in implementation, it assumes input will be \[0,1\]. So now user can specify it up to 100, which makes AM can use 100x of queue capacity. We should fix that.
