-----------------------------------

             Summary: adoop-yarn-server-nodemanager's use of Linux /sbin/tc is non-portable
                 Key: YARN-3773
                 URL: https://issues.apache.org/jira/browse/YARN-3773
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
         Environment: BSD OSX Solaris Windows Linux
            Reporter: Alan Burlison


hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/container-executor.c
makes use of the Linux-only executable /sbin/tc (http://lartc.org/manpages/tc.txt)  but there
is no corresponding functionality for non-Linux platforms. The code in question also seems
to try to execute tc even on platforms where it will never exist.

Other platforms provide similar functionality, e.g. Solaris has an extensive range of network
management features (http://www.oracle.com/technetwork/articles/servers-storage-admin/o11-095-s11-app-traffic-525038.html).
Work is needed to abstract the network management features of Yarn so that the same facilities
for network management can be provided on all platforms that provide the requisite functionality,
