Yufei Gu commented on YARN-7247:
--------------------------------

[~balloons], this is not a problem of multi assignment. You are basically 
asking for anti-affinity. Please check YARN-1042 (add ability to specify 
affinity/anti-affinity in container requests).

> Assign multiple will lead to hot point problems of physical resource 
> consumption
