Description

hadoop 3.1.3
Capacity Scheduler

Faced with a limit limit in Capacity Scheduler
yarn.scheduler.capacity.maximum-applications
The default value was set to 10000
At the same time, we have no more than 150 tasks running, while there are 0 in the launch queue
At the same time, I noticed that the data on active tasks in the first version http://YRM:8088 and the second version http://YRM:8088/ui2 differ

Is this a bug or do we misunderstand the implementation of these Capacity Scheduler settings ?
