Sidharta Seethana commented on YARN-3366:
-----------------------------------------
[~hex108] , The goal here is to allocate a maximum amount of bandwidth for YARN
containers - irrespective of whether strict mode is enabled or not. Strict mode
only determines per-container behavior and I am not sure it makes sense to
extend its semantics to include other behavior. It is possible to set
yarnBandwidthMbit to the same value as rootBandwidthMbit either by explicitly
setting its value to be equal or not setting it at all ( in which case the
behavior is to assign yarnBandwidthMbit to the value of rootBandwidthMbit).
I recommend filing a separate JIRA in case you think we should be changing
this, since the patch for this has been committed already.
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
