Sidharta Seethana commented on YARN-3366:
-----------------------------------------

hi [~hex108] ,

The goal here is to ensure that we have a maximum assigned bandwidth for all 
YARN containers when cluster admins require this. The behavior you want (where 
YARN containers are allowed to use the total bandwidth) is possible by simply 
not configuring max YARN outbound bandwidth - in which case it defaults to the 
total bandwidth. 

thanks

> In order to be able to isolate based on/enforce outbound traffic bandwidth 
> limits, we need  a mechanism to classify/shape network traffic in the 
> nodemanager. For more information on the design, please see the attached 
> design document in the parent JIRA.
