Subject [jira] [Comment Edited] (YARN-7247) Assign multiple will lead to hot point problems of physical resource consumption

[~templedf] Thank templedf. But it was a very difficult choice for us: 
* Turning on the dynamic assignment will cause the same resource consumption type of container
placed on one node.
* Turning off the dynamic assignment will lead to very bad scheduling performance.

So, I want the fair scheduler to support turn on multi assignments, but each time the resource
is allocated to a different application.
What do you think?
