             Summary: Capacity Scheduler max AM resource percentage is mis-used 
as ratio
                 Key: YARN-3153
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wangda Tan
            Assignee: Wangda Tan
            Priority: Critical

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.
