Yufei Gu Hi, yufei. I am sorry for take your attention to this JIRA.
I don't know whether the JIRA is useful to others but is very useful for me.
Because in fair scheduler it will check whether the am used resource over limit
when assign container to a application. We can see the logic as follow:
So it is useful to check whether the am used resource is over limit by RM web ui.
But I don't know whether it is need for others.
Can you help me review my patch? If you think it is not useful for others, can you help
me close my patch?
