> Support bandwidth enforcement for containers while reading from HDFS
> --------------------------------------------------------------------
>
> Key: YARN-2681
> URL: https://issues.apache.org/jira/browse/YARN-2681
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: capacityscheduler, nodemanager, resourcemanager
> Affects Versions: 2.5.1
> Environment: Linux
> Reporter: cntic
> Attachments: HADOOP-2681.patch, HADOOP-2681.patch, Traffic Control
> Design.png, yarn-site.xml.example

>
> To read/write data from HDFS on data node, applications establise TCP/IP
> connections with the datanode. The HDFS read can be controled by setting
> Linux Traffic Control (TC) subsystem on the data node to make filters on
> appropriate connections.
> The current cgroups net_cls concept can not be applied on the node where the
> container is launched, netheir on data node since:
> - TC hanldes outgoing bandwidth only, so it can be set on container node
> (HDFS read = incoming data for the container)
> - Since HDFS data node is handled by only one process, it is not possible
> to use net_cls to separate connections from different containers to the
> datanode.
> Tasks:
> 1) Extend Resource model to define bandwidth enforcement rate
> 2) Monitor TCP/IP connection estabilised by container handling process and
> its child processes
> 3) Set Linux Traffic Control rules on data node base on address:port pairs in
> order to enforce bandwidth of outgoing data
> Concept:
