Rajiv Chittajallu commented on MAPREDUCE-4168:
----------------------------------------------

bq. Rajiv Chittajallu - are you proposing to not support multiple network interfaces? If so,
could you please open another JIRA (or a discussion thread on yarn-dev) along with why the
current approach is bad, and how the new proposed approach is better?

Requirements mentioned in HADOOP-8198 can't be addressed by adding support for multiple network
interfaces. Its being assumed that, both networks are implemented as Layer 2 and interface
routes are sufficient. With current networks, scope of Layer 2 is limited to rack switch.
There are much simpler alternatives to the challenges being addressed here.
