[jira] [Commented] (MAPREDUCE-4168) Support multiple network
interfaces
[ https://issues.apache.org/jira/browse/MAPREDUCE-4168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14266674#comment-14266674 ]
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.
