Vinod Kumar Vavilapalli updated YARN-2681: ------------------------------------------ Target Version/s: 2.8.0 (was: 2.7.2) Moving new-features out of 2.7 maintenance lines into 2.8.0. > 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: nodemanager > Affects Versions: 2.5.1 > Environment: Linux > Reporter: Nam H. Do > Labels: BB2015-05-TBR > Attachments: Traffic Control Design.png, YARN-2681.001.patch, > YARN-2681.002.patch, YARN-2681.003.patch, YARN-2681.004.patch, > YARN-2681.005.patch, YARN-2681.patch > > > 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: http://www.hit.bme.hu/~do/papers/EnforcementDesign.pdf > Implementation: > http://www.hit.bme.hu/~dohoai/documents/HdfsTrafficControl.pdf > http://www.hit.bme.hu/~dohoai/documents/HdfsTrafficControl_UML_diagram.png -- This message was sent by Atlassian JIRA (v6.3.4#6332)
