Description
Currently maximum applications is expected to be calculated as follow according to priority when using percentage based capacity:
(1) equals specified maximum applications for queues
(2) equals global maximum applications
(3) calculated as queue-capacity * maximum-system-applications
But for absolute resource configuration, maximum applications is calculated as (3) in ParentQueue#deriveCapacityFromAbsoluteConfigurations, this is a strict limit for high max-capacity and low capacity queues which have little guaranteed resources but want to use lots of share resources. So I propose to share the maximum applications calculation of percentage based capacity, absolute resource can call the same calculation if necessary.
