Sidharta Seethana commented on YARN-3773:
-----------------------------------------

Hi [~alanburlison],

Could you please elaborate what you are referring to here?

The code in question also seems to try to execute tc even on platforms where it will never
exist.

The container-executor binary is only used by the LinuxContainerExecutor - so I am wondering
what you meant by this. 

thanks,

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,
