Description

When I set yarn.scheduler.capacity.<queue-path>.capacity and yarn.scheduler.capacity.<queue-path>.accessible-node-labels.<node-label>.capacity to absolute resource value, staring RM fails, and throw following exception, and after diving into relate code, I found the logic of checking absolute resource value maybe wrong.
