Subject [jira] [Commented] (YARN-3366) Outbound network bandwidth : classify/shape traffic originating from YARN containers
Date Thu, 30 Apr 2015 03:28:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-3366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14520788#comment-14520788
] 

Jun Gong commented on YARN-3366:
--------------------------------

When addYARNRootClass in TrafficController#initializeState, could we set its ceil rate to
rootBandwidthMbit instead of yarnBandwidthMbit? Then YARN could use more network bandwidth,
and it will not affect defaultClass because its rate has been set to defaultClassBandwidthMbit.

> 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.
